    Oddly enough, about a year ago I suggested wiring the embedded device we were working on with thermite so that if one of those wise-ass kids in Sweden tried to hack our hardware, it'd quitely fry the motherboard and hard drive. Of course, they'd have to be careful about the amount. It's kinda bad PR if the wise-ass kid loses an arm in the deal. I'd call that a feature rather than a bug though (It certainly would discourage hardware hacking.)

    In retrospect I should have patented the idea. I could probably get some decent royalties from assorted intelligence agencies around the world.

    If you're from one of aforementioned intelligence agencies, there are lots more ideas where that came from hint hint...

    anyway... this just doesn't sound all that "new"...

    205 laptops going missing (even if it is since 1997) is still a rather alarming number, considering their contents.
    Maybe they should chain them to the owners. :)
  • Its all fine and dandy that you can blow up a laptop, but thats expensive. Make the people pay for the lost equipment. Me, i'd make damn sure that I didn't leave behind a laptop worth $6,000 dollars. Or, have like a wristwatch that transmits a signal, and if you get say, 20 metres away from your laptop it goes off. An ounce of prevention beats uhh.. a lot of cure? Anyways, the idea that a laptop could self destruct is always nice, keep the data on it encrypted for added security.

  • That leave their laptop in a bar after getting drunk.

    Thieves have been blamed for some of the laptop losses, but the majority of the missing machines were simply mislaid by tipsy or distracted agents.

    Kind of makes you wonder just how hard it is to get a job as an international spy. Maybe the really good spys are the ones who go to the bar, get some agent a few drinks, maybe with some GHB alongside, and then the next morning:

    Why are you even taking the laptop with the bomb plans to the bar? Do they have weapons grade drink recipes on the same hard drive?

    One thing that seems to bemuse foreigners about Britain is the fact that the Kingdom punches above its weight in international affairs.

    One of the main reasons for this is the historical tradition in Britain to rule over peoples and waves, since the days of William the Conqueror. The British have always had a caste system based on gearing the country to wage war, and to rule other countries. The British upper classes are bred to lead over others, even genetically speaking this can be seen - every president of America has been of stout Anglo Saxon extraction.

    The result of all this is that the British can exert huge influence abroad, and even today the pax Britannica continues, through our proxies, the Americans, who inherited their ideals from us.

    The shining light of Celtic inventiveness and Anglo Saxon ruling and liberty has meant that every corner of the globe has had the values of liberty and democracy enforced upon it. America would not exist were it not for the Mother country.

    The secret services are trusted by the British people, as they are composed of boarding school, cricket playing chaps who have been steeped in playing 'the game' since childhood. This tradition is why Britain was aware of the Soviet threat before america, and managed to convince america to join us against the Soviets. Same with Hitler - the Americans were to scared, and thought he was no threat. But Britain nobly stood alone.

    In this laptop, we see the traditions of Old England and Empire distilled to a pure essence : Trust noone, treat all fairly and always some first - tho' 'tis no shame to come second, something that our American children have perhaps forgotten.

  • Yahoo [yahoo.com] has the story about the "missing" laptop here [securityfocus.com]. It seems that A Defence Ministry laptop computer packed with national security secrets had gone missing after an official left it in the back of a taxi. The official had notified police about the missing laptop but nothing has come out of it. Anyway as the story said this is not the first time: In March last year there were reports that agents of MI5, the domestic security service, and MI6, the overseas security service, had lost laptops containing secret information.
  • I had an Apple Powerbook 5300cs (code name: Hindenbook) that already had this self-distruct technology years ago.
  • It would sure help make people honest. Sure, that laptop you're illegally pilfering is probably not rigged to explode in your face... but how can you be sure? Best to just leave it exactly where you found it.

    And you could extend this to other items as well. Every retail shop could come equipped with one or several decoy items, so if the place gets ransacked, the thieves would either be trackable, or better yet, you could detonate the payload, either something destructive, or something the equivalant to a dyepack.

  • Hopefully the agents who are losing their laptops aren't doing anything super secretive, lord knows if they lose a typical laptop, imagine what could happen with some super secretive 2inch chip ;\

    To combat this spate of missing-in-action machines, the Defense Ministry plans to outfit their absent-minded workers with secret-agent-style briefcases that protect national secrets by automatically destroying the contents of lost laptops' hard drives.
    Shit I could write them a script to do this after three failed attempts, and securely wipe their data beyond comprehension [antioffline.com]. What they should do is give those agents time off with a suspension, ultimately leading to being fired for incompetence and negligence.

    Odd that an MI6 agent would be out bar hopping with her laptop. I know the UK is a bit more relaxed then we are out here in the US, however I still can't grasp losing a laptop, let alone going to a bar with a laptop that had gov secrets on it if I intended to get hammered.

    Maybe their government should look into a biometrics fingerprint based system which wipes a laptop on a failed attempt.

    By purchasing something like some super elite case, I'm sure those laptops which were stolen will be easier to target the next time around.

    Is it because its more trendy than a desktop or something? Even if this is the case, who cares? Why does the intellegence community need them? If data is sensitive, even in the slightest, it shouldn't EVER be in a position that it could be accidently LEFT LYING AROUND SOMEWHERE! It should remain confined within a secure guarded perimeter. Even when kept internally it is subject to potential security breaches, networks can be cracked, spies can smuggle out information, etc, but at least thats a far cry than being able to just pick up a 4 pound object and walk away with it and spend all the time you need trying to figure out what you have.

    Besides this reason, laptops are fragile, expensive, and rarely contain many user servicable parts. Even if you were going to set up a system in a public environment, would you prefer your potential thief to be forced to lug around 40+ pounds of bulky equipment or be able to slide 4 pounds worth of equipment into a backpack and walk away?

  • There are (at least) three extremely good packages available for performing seamless, convenient, on-the-fly encryption of your hard drives. I can't believe they are stupid enough to not only neglect to use one, but also to propose an unreliable physical 'bomb' to destroy the drive! C'mon!

    Scramdisk, E4M, and PGPDisk all create 'virtual' mounted disks on your system, which act just as any normal disk. When you boot up, you run the software, 'mount' the virtual disk (it's a large file on your hard drive), and voila. You have a fully high-strength encrypted volume to use just like you would any other disk. Very, very easy. You can even install your apps there if you want.

    The data itself is encrypted on the fly, and stored on fully encrypted form on the disk. Therefore, if the volume was unmounted (say, by rebooting), the data is totally unaccessible. If you just rely on your computer to kick into password-protected 'sleep' mode, or use a password-protected screen saver, you're pretty well covered - the only way you can really get by these things is by rebooting - which unmounts the encrypted disk. Abracadabra.

    Everyone in business who travels with a laptop should be using software like this. Scramdisk is, in fact, free (Win98/ME, $20 for NT/2k), and open source! I believe E4M is free, as well (not sure about the source).

    Take a look:

    Scramdisk [clara.net]
    E4M [e4m.net]
    PGP [pgp.com]

    Why this stuff isn't more universally used by laptop-travelers, especially government-secret or business-secret toters, is absolutely baffling. Hell, it's even easier to use than public-key encryption.

  • Motion sensors & drive encryption (Score:3)

    by Fencepost ( 107992 ) on Tuesday April 17, 2001 @02:43PM (#284664) Journal
    Take a look at this article [computerworld.com] from Computerworld a couple weeks ago.

    Basically what the manufacturer is working on (it's not available yet) is a motion sensor and alarm, tied in with some form of drive encryption. Move it far enough that it thinks it's being stolen (user-configurable parameters) and it bluescreens the system and won't restart without a 16-digit code; the drive contents are protected because they're encrypted using keys built into the motion sensor system.

    This is far from optimal:

    • it presumably requires some significant driver support and will probably be limited to Win2k initially;
    • anyone serious enough about it may be able to extract encryption keys from the device itself;
    • hm, 16-digit number.... Guess I'll have to go through the guy's garbage for his credit card numbers;
    • it's not available (though apparently betas exist).

    Still, at the moment there aren't a lot of other options out there either. I'd expect to see quite a few more products along similar lines cropping up in the next few years.

    There are certainly more effective possibilities out there....

    One possibility would be a combination of hardware-level drive encryption keys and this sort of motion-sensor setup to keep the system from being stolen while active. Keys would be read from a removable device (iButton- or USBKey-like) as part of the power-up process and would be kept in RAM. Removing the key device would trigger a hardware-level system lock (many notebooks have these already, completely independent of the OS) but the system could keep running. Because the system stays on, it remains easy to step away from it while leaving it well protected - requiring the key to be present for drive access would be much more troublesome, because it would mean either shutting down or hibernating the system or having the OS aware of the protection so disk activity could be prevented without the key. This could be done almost entirely independent of the OS, with a fairly simple interface to make configuration changes.

    Same with Hitler - the Americans were to scared, and thought he was no threat. But Britain nobly stood alone.

    I am sure France, Australia and New Zealand will take exception to this. Those three countries, along with Britain, declared war on Germany on September 3, 1939. Incidentally, two days later the US declared neutrality and wouldn't join the war for over 2 years.

    One of the main reasons for this is the historical tradition in Britain to rule over peoples and waves, since the days of William the Conqueror.

    But wasn't William the Conqueror French? Hence the name "The Conqueror" - he conquered England. Surely a better were argument would be that, as one of the most invaded countries of Europe (France, Germany, Italy, Scandinavia .... the only ones we really stopped were the Spanish), Britain decided enough was enough, she was no longer going to take this anymore and decided to do some invading for herself?

So when the PC's/Laptops were stolen, they contacted Distributed.net, who went through the keyserver logs and found the IP address of the stolen computer. This information was turned over to authorities and the stolen computers were traced to the thieves and returned to their rightful owner(s).

    One thing that seems to bemuse foreigners about Britain is the fact that the Kingdom punches above its weight in international affairs.

    Quite not. The britshit are totally decadent. And they are one of the most hated people on earth.

The British upper classes are bred to lead over others, even genetically speaking this can be seen - every president of America has been of stout Anglo Saxon extraction.

    The britshit ruled other lands because they depleted the meager natural ressources on their puny island. They had no other choice but develop the skills, laws and institution that allowd them to rape, plunder and pillage the whole world.

    Did you know that once, you used to be able to purchase a piracy license, hire a crew, and legally go on the high seas and plunder and pillage non-britshit ships?

    The result of all this is that the British can exert huge influence abroad, and even today the pax Britannica continues, through our proxies, the Americans, who inherited their ideals from us.

    Some pax! Just a heavy navy that went all over the place, and whenever a britshit merchant wasn't able to pillage and plunder to his content, they simply bombarded the shit out of the place that had the guts to say no to some britshit swindler.

    And to meddle in European affairs by instillating wars between the countries to insure that no one would turn against the britshit. One will remember Neville Chamberlain's accommodation with Hitler, which allowed the latter fucker to plunder Europe unmolested until it was almost too late!

    The shining light of Celtic inventiveness and Anglo Saxon ruling and liberty has meant that every corner of the globe has had the values of liberty and democracy enforced upon it. America would not exist were it not for the Mother country.

    Anglo saxon "liberty" is only affordable to the richer, those who are able to afford armies (of lawyers or soldiers - some britshit croporations used to have their own private armies) to defend their own liberty, at the expense of others, of course (like Mc Donald's bludgeoning critics to death by suing them for slander).

    The secret services are trusted by the British people, as they are composed of boarding school, cricket playing chaps who have been steeped in playing 'the game' since childhood. This tradition is why Britain was aware of the Soviet threat before america, and managed to convince america to join us against the Soviets. Same with Hitler - the Americans were to scared, and thought he was no threat. But Britain nobly stood alone.

    Those boarding school cricket players are the epitome of britshit incompetence, as exemplified with the incompetent family-compact, which was unable to keep their empire at the end of the war. And the britshit appeased Hitler to the end, so talk about shitting in one's pants!!!

  • The British aren't ruled by the upper classes- the 'caste system' has almost disappeared, and the cabinet isn't all from Oxbridge, isn't all from a privileged background and John Major, the last Prime Minister and son of a circus performer, made his career from standing on soap boxes. Most people are middle class. Hugh Grant is as representative as Captain America.

    The Secret Services have come under a lot of scrutiny following memoirs and a budget that has been rocketing despite the end of the Cold War. Read the papers. Despite a resurgence we're terrible at Cricket because it's not getting played very much any more- even in boarding schools it's usually third to Football and Rugby.

    The British Government has a nasty habit of acquiescing to America, particularly when the Americans want to bomb someone. As a Nation we tend to follow where the EU or the USA leads.

    The key is hashed right directly from the passphrase. With the passphrase, you can mount the drive. Without it, you can't. No need for keydisks and whatnot. Scramdisk even has provisions for hiding its own existance.

    For any decent passphrase, breaking it will be impossibly difficult. Sure, with an 'unlimited' amount of time, but no one has 10^20 years to do it.

    This method is totally viable, and successful. Read up at alt.security.scramdisk .

    There's been a lot of discussion of various ways to encrypt drives for protection, and also of ways to cause drives to self-destruct. The problem with the encryption systems is maintaining the secrecy of the key, when the attacker has access to all the hardware and software. The problem with the self-destruct systems is keeping things sufficiently controlled to destroy the data but not hurt anyone.

    The following synthesis makes sense to me: Have the drive encrypted with a symetric-key cipher. Have the key stored in NVRAM or some equivalent. In normal operation, the encryption and decryption is handled transparently. either by software drivers, or (better yet) by the drive controller itself. Because no person needs to know the key, it can be truly random and long enough. To activate the self-destruct, simply erase the key. I don't know much about NVRAM, but I imagine that it is possible to "wipe" it sufficiently that the data can't be recovered. If not, this idea would have to be modified.

    In the best-case scenario, all of this functionality is integrated into the drive controller, so that data is encrypted before it's sent to the disk, and decrypted before it's returned to the system bus. This makes life easier for everyone since the encrypted drive system looks just like a normal IDE (or SCSI) system from the outside. More importantly, it means that the key can be stored inside the controller card, and never needs to be made available to any other hardware or software. This minimizes the risk of key compromize, even by a malicious user.

    The card would have to support an instruction (or physical connection) whereby it could be signalled to self-destruct. This could be activated by LoJack-style equipment, or what have you.

    Once the key's truly erased, the contents of the drive become totally unusable.

  • Israel's been using similar kind of stuff to kill Arab terrorists for years. The most famous instance was back in 95 I believe. A terrorist nicknamed "The Engineer," took his cell phone in for repairs. The Israelis booby-trapped it with plastic explosives and after he got it back from repairs they called him to make sure he had the phone and detonated it remotely. The Arabs have been using simmilar techniques. They plant bombs in a public place like a restaraunt which have a cell phone as the detonating mechanism. After they're out of the area they call the cell phone and boom.

  • When I read the bit about rigging the laptop case so that it would destroy the data on the hard drive if opened I thought, "short of physically destroying the disk, it won't work."

    Unfortunately, erasing data is harder than you think. There was an article on rootprompt sometime back (sadly, I only saved a text copy of the article, not the URL; the author is Dr. Peter Gutmann of the CS Department at the University of Auckland) which went into some detail on what you would have to do. It was a long article and had many technical details, but the one sentence summary is this: "you have to overwrite the entire drive at least 35 times with a special set of bit patterns". Think how long that would take on a 20G drive (what my own laptop has)! I doubt the battery would be up to it, even if they didn't detach it.
  • Store the primary encryption key on tamper-resistant hardware like an iButton. That's designed to destroy the data onboard if anyone tries to open the case, without the need for messy explosives, and the steel case means the tamper resistance is pretty good.

    Then use the passphrase to negotiate with the iButton for the key onboard. Unless you can defeat the tamper-resistance, bang goes any hope of dictionary attacks on supercomputers; you have to try each passphrase against the iButton, and it will impose longer and longer delays between tries. A strong password protocol like SRP will prevent some attacks based on this system.

    Now the security from your passphrase is vastly greater. The iButton is pretty dinky and can be kept on your keyring (the thing that has your house keys on it, not a PGP keyring); it's unlikely you'll leave it in the back of a taxi alongside the laptop.

    Of course the primary key is a proper high-entropy key (100 bits or more) so there's no hope of a brute force attack.

    Does that sound secure enough?

    As usual, Big Blue has an answer [ibm.com].

    Their TravelStar (and DeskStar, too) hard drives support the use of a password. The system's BIOS has to support it, but if it does (like the Dell Latitude's, I think), the hard drive will not permit any read or write commands to data areas. There's a master password which can be set to override the user password, but if you control both, and forget both, the only way to get the hard drive back is to send it a special command which will cause it to erase the entire user-accessible data area, then unlock itself.

    Don't bother trying to change the logic board, either -- the passwords and settings are stored on a non-externally-addressable area on the platter.

  • That's nice they are going to spend that much money on the special briefcases. I have a slightly better plan. How about NOT PUTTING NATIONAL SECRETS ON A GODDAMN LAPTOP. And on the occasion you do really need to, do the cliche and handcuff it to the couriers freaking arm. Let's see them leave it in a taxi then. Both the British and U.S. have had appalling breaches of security with portable computers and devices. What I think really needs to happen is for the system and or security admins to get more authority to tell some of these people how to operate. Give the admins enough authority to tell the little scientists and agents that "hey, I'm sorry you find this inconvenient, but, you're working with whatever national secrets. Too freaking bad, deal with it". Then maybe you won't have missing laptops and harddrives(Los Alamos) as often.

  • Who ever comes up with the totally secure computer will probably make more than a ripple in the computing world.

    We all know that any computer can be cracked... It's just a question of time.
    I like the idea of having a program that you must go through first. A password that only allows three incorrect entries. There's no way around this password mind you...
    After three entries the computer starts to erase itself (format if you would..). The program will shove a file in the registry at the same time. This will ensure that even if the computer is shut off the HD will resume erasing when turned back on..

    Or take it a step further, have all of that plus a secret battery in the computer / laptop that is constantly being recharged by the bigger battery. This secondary battery has just enough charge to allow the computer to format itself. That way in the event of a force opening and format if the culprit tries to turn off the computer to prevent the formatting, he/she/they can't.

  • Hey.

    We have cameras covering every square inch of Britain so that every individual can be tracked.

    Actually, no. Cameras are rarely placed anywhere that doesn't have a fairly high risk of crime. In the center of the shopping district in a city yes, there may be cameras. But not in suburban housing areas, et cetera. That would be stupid.

    But we can't tell you where Agent 69 was last Tuesday when he lost his laptop.

    Unfortunately, most cameras are on the street, i.e. where a lot of street crime is committed, not in the back of taxis, or behind bars. In any case, the resources required to track any person using security cameras would be massive. Whenever they entered a covered area, there would be a risk of them not being picked up again. Have you ever tried to identify someone from a fuzzy, black-and-white security camera? It is sometimes difficult.

    And it's a good thing we've got these cameras to keep track of the IRA, or they'd set up us the bomb.

    Can't live with them, can't legally torture them to death...

    So we'll give each agent a small thermite bomb in a briefcase instead, and give 'em free roam of the city.

    If we look at the article:

    the Defense Ministry plans to outfit their absent-minded workers with secret-agent-style briefcases that protect national secrets by automatically destroying the contents of lost laptops' hard drives.

    I very much doubt Thermite would be involved. Why not just make a thin iron lining for the briefcase, then take it out and wrap a thin wire around it, say, 10,000 times, then connect it to some capacitors and a battery inside? If you open the case without entering the code, the (ready-charged, of course) capacitors burst-discharge, like a camera flash, into the wire coil with the iron center, and the laptop in it. As those of you who were awake in first year high school physics may have guessed, you have a big electromagnet, with your computer inside is, recieving a big burst of voltage. This would generate a substantial magnetic field. Since hard disks are written to magnetically, Bang! All the data is erased.

    That would be far safer and similarly effective.

    But why they don't just encrypt the hard disks is beyond me.

  • Hey.

    If someone hacks your computer, the worst thing that could happen is you'd lose some data and have to do a fresh install of everything. If you put fucking thermite in a PC, you're out $2000 worth of hardware.

    If we look at the original post (emphasis mine):

    about a year ago I suggested wiring the embedded device we were working on with thermite so that if one of those wise-ass kids in Sweden tried to hack our hardware, it'd quitely fry the motherboard and hard drive.

    An embedded device isn't a desktop computer or a server. It's a proessor that's 'embedded' in another device. Take a TiVo [tivo.com] for instance. It is an embedded device. The original poster's usage of the term 'hack' was not as in crack [tuxedo.org] but as in 'classic' hacking [tuxedo.org].

    The definition is important. If I was to crack a server, I would be breaking in and acessing data without authorisation. If I were to hack an embedded device, I could for example add more recording time to my TiVo [outflux.net].

    Some companies are annoyed by peope hacking thier embedded hardware, since they can but low-spec versions and make them into high-spec versions.

    The original poster was likely making a joke. He proposed a device that if you opened the case to upgrade it, would destroy itself.

    It's funny. Laugh.

  • Q: and try to bring it back in one piece, 007.

    Bond: Yesh, Q.
  • It was a Tivo-like device the brand name to which I will not name. Management explicitly stated they didn't want people to be able to upgrade the hard drive. They also had requirements from the MPAA to incorporate copyright contros so that people wouldn't rip the hard drive out and post episodes of Dharma and Greg on the Internet. Hack or crack, they didn't want it happening. A tiny little speck of thermite to fry the circuitry on the motherboard and hard drive would have done the trick quite nicely. They didn't go for the suggestion, though. I'm rather surprised really. They had the right mindset.
  • Passphrases are typically low entropy beasts; a brute force attack tends to be effective against them if you can gather a decent wodge of computing power. You can use key stretching to make things harder, but that only gets you so far.

    So the point of the primary key and tamper-resistant hardware approach is that the attacker no longer has the option of trying passphrases on their supercomputer. With what I'm suggesting, the only way to try a passphrase is to try and use it to log into the iButton. The iButton gets to decide how often you can try in a given time period, and for how long it'll lock you out if those attempts fail. That's vastly more secure.

    Also, you now need two things to break in: the passphrase and the bit of hardware. Even if they've used "password" as their password, stealing the laptop still isn't enough; and you're much less likely to leave the iButton lying around anywhere.

    Obviously the passphrase will be hashed as part of the key stretching protocol, and obviously you design things so that even if you can break the tamper-resistance you still have to brute-force the passphrase, but the iButton adds a very significant extra hurdle that could really make the difference for security.

  • British intelligence officers have developed a rather worrying tendency of forgetting that they are carrying a computer, leaving a trail littered with lost laptops. The British Defense Ministry has reported 205 laptops missing since 1997 -- most of which contained classified information. That's an average of 51 lost laptops per year.

    Right from the article. Which word do you see more, lost or stolen? Do you get off on writing inane shit when you haven't read the fucking article?

  • You don't store the key in the machine, where you have to trust your system to erase it. You have the key entered by the user when they boot. No key, no valid blocks decrypted from the disk. There are plenty of encrypting file systems that do this correctly, though probably others that botch the job (:-) If you want better randomness than that, yes, store additional bits somewhere like NVRAM or on the unencrypted parts of the disk, and hash them together with the user's passphrase to get the drive key.


    In practice, it's tough to put the drive encryption on the disk controller, especially for laptops where the controller's integrated into the motherboard. (Most desktops also integrate it, but you can still run a separate controller board.) Either put it in the disk drivers (so you're writing encrypted blocks to the disk, but not changing the file system code), or else put it in the file system code (which has different limitations, but is much more friendly about keeping encrypted and unencrypted partitions, e.g. /usr can be unencrypted read-only while /home and /swap are encrypted.)

  • 16 digits? That's only ~48 bits, which is way lame, and doing decent encryption doesn't take any more work. And yes, that does invite use of a credit card number as the key, which maybe safer than some kinds of numbers because you won't leave it on a yellow sticky note next to the computer but is otherwise wildly insecure. (Especially to anybody who wants to spend a few bucks on a credit report :-)
  • Definitely, encrypting the drive is cheaper, much more effective, and also doesn't require carrying your 2-kg laptop in a 10-kg armor-plated bullet-proof phone-home-capable handcuff-equipped trenchcoat-color-coordinate briefcase (although that can be 31337 k00l if you're into that sort of thing :-)


    Fundamentally, this is a case of governments shooting themselves in the foot with anti-encryption policies.* While there are encrypting file systems available, including commercial and freeware, they're not universal, hardware support for encryption and encrypted disk drives aren't universal, and lots of products are dumbed down to 40-bit or 56-bit crypto because of US export laws and those of other countries which the US talked into adopting. Many of the policies had the pretense, or sometimes the serious motivation, of keeping Commies from getting crypto, because we all know that Commies can't read math books and write software using them, but in large part they were supported and promoted by civilian wiretapping enthusiasts like the US FBI and the UK Home Secretary, who want to be able to keep track of everything their subjects** do, say, write, read, or look at. Instead, they're endangering the security of their military secrets, making it more likely that Commies and Terrorists can get them from stolen laptops and other unencrypted and underencrypted sources like GSM cell phones.


    * OK, it's partly the US government helping the UK government get shot in the foot, but Louie The Freeh and Mr Jack Straw really deserve each other...


    * Yes, US Citizens aren't technically subjects, and UK people are subjects of the Queen, not the Home Office, but that's not how the internal police forces *feel* about them....

  • The difference is:

    1) In the UK, the lappys were still government property, and the easiest way to make them personal property is to "loose" them.

    2) while the students were "given" the laptops; why "loose" something you don't haveto give back.

    I've seen this type of loss a lot in corporate america, why should the UK be any different.

    btw - when lappys get too old/slow, their owners get very clumsy.."I was working on my balcony and the damn thing dropped 30 feet onto the concrete", returning the pieces in a plastic WallMart bag.
  • Ah yes, and what happens when they open the briefcase and see the post-it note with the encryption key is stuck on top of the laptop? What they're looking for is a foolproof way of protecting their information. Encryption is only as secure as the protection provided to(not by) the key.
