Lockbox Aims To NSA-Proof the Cloud 292

Daniel_Stuckey writes "Lockbox, a tech startup founded in 2008, just received $2.5 million in seed funding for its end-to-end encryption cloud service, Client Portal. So, how does end-to-end cloud encryption work? Lockbox encrypts and compresses files before they are uploaded to the cloud. Only a person in possession of the corresponding key can unlock, or decrypt, the files. This means that the NSA, malicious hackers, business competitors, and even crazy girlfriends and boyfriends won't be be able to peer into users' most sensitive and private files."

      A friend of mine offered that kind of service quite a few years ago.

      It was a backup service. The user had the key. It was encrypted on the user's site, and only encrypted data sent up to the server.

      It's not novel. It's a slashvertisment. {sigh}

          Tarsnap should also be mentioned in this context. It's a business started by Colin Percival, noted cryptographer and BSD developer. The client is 100% open source and runs on your machine. When Colin developed Tarsnap he found existing key derivation functions lacking, so he developed his own memory hard scrypt, which has found wide applications in other areas.

          The major problem with "encrypted cloud" solutions is that encryption severely limits what can be done in the cloud. You can basically do encrypted file storage. You can't run virus or spam filters on your data, you can't index it and search it etc. So all the useful features we have in a Gmail session need to awkwardly and inefficiently be re-implemented on the client side.

          The providers have very little incentive to do this and transform ad supported free services into paid ones (since data mining no longer works, ad revenue drops dramatically). While I would love encrypted email for everyone, it just won't happen for economic reasons. The NSA affair will be quickly forgotten and people will return to business as usual.

            Full homomorphic encryption is really hard. Homomorphic encryption allows you to encrypt your data, do some computation on the result, and then perform some operation on the output to get the same result as doing the operation on the unencrypted data. Current solutions are at least a factor of 1000 slower than doing it on unencrypted data, but that's only for general case. There are ways of encrypting data that preserve certain properties so you can, for example, perform simple database operations on it in the encrypted form and only interpret the results if you hold the keys. The down side of these approaches is that they increase the size (effectively doubling it for every primitive operation that you want to support), but with storage becoming cheap they may become interesting...

          I use CP as well, with a private key. How do you know that they haven't sent that private key to their servers? I don't, but I'm pretty sure they won't do this by default. If it comes out, it's not good for their business. But how about an obfuscated command that tells the local backup program to send the key to them? It would only be used rarely, so it won't be discovered quickly. Can you assure me that such an option does not exist? I can't.

        Another service offering:

        SpiderOak uses AES256 in CFB mode and HMAC-SHA256. SpiderOak uses a nested series of key scopes: a new key for each folder, version of a file, and the individual data blocks that versions of files are composed from. Having keys with such limited scope allows for selective sharing of chosen portions of your data while keeping the remainder private.

                Most importantly, however, the keys are never stored plaintext on the SpiderOak server. They are encrypted with 256 bit AES, using a key created from your password by the key derivation/strengthening algorithm PBKDF2 (using sha256), with a minimum of 16384 rounds, and 32 bytes of random data ("salt"). This approach prevents brute force and pre-computation or database attacks against the key. This means that a user who knows her password can generate the outer level encryption key using PBKDF2 and the salt, then decipher the outer level keys, and be on the way to decrypting her data. Without knowledge of the password, however, the data is unreadable.

                SpiderOak accounts also include a 3072 bit public/private RSA key pair. This is currently not used for anything, but is included with all accounts with the expectation that SpiderOak will add multi-user private collaborative and sharing features which would necessitate the use of the the public/private keys.

      It would defeat the point. You can probably safely assume they are not sending them right now.

      The problem is: in the future, when more than 2 people start using their service --- the chance gets higher and higher over time, that NSA agents will descend upon them, and provide a legal order requiring they insert backdoors into their service, or protocol, or otherwise: provide the NSA with the resources required to get at the content, AND requiring they tell nobody.

      In other words : No US-based cloud service can really fight the NSA; unless they are prepared to shutter the service and go to jail for the cause, which is not likely.

      An overseas service is even better for the NSA getting a better chance at capturing the data -- because the things that are legal for them to do expand; gathering intelligence on overseas communications falls within their government mandate; and the techniques they employ could espionage, infiltration into the organization providing the service; and include compromise of computer systems and implanting malware bugs.

        I don't think an overseas service is better for the NSA. They don't have to even pretend to have ethical or legal constraints, but they are limited by international politics. They are stuck asking for cooperation. Or trying to bribe the right people. Within the US they have the full force of the US government behind them and can simply put uncooperative people in jail.

        Nevertheless things have reached a point where you might get idealogically motivated people starting anti-NSA encryption systems and there isn't much the NSA can do against someone willing to risk prison or flee the country or shut down their entire company rather than deal with the devil. The NSA and the government in general are used to dealing with people who are easily controlled with nothing more than money.

        But, yeah, the NSA can at least shut down pretty much any US based centralized system intended to fight them. Outside of North America and Western Europe it's a different story though. They don't have any legal power to shut down anything over there.

You may think that somewhere like Venezuela hates the US enough to allow a business like this but I guarantee that the average sys admin in Venezuela could be bought for a few hundred.

        That's not Exactly true.

        If a service provides an open source encryption routine, and also, perhaps, but not necessarily required, an open source transfer routine for the already encrypted files, you could air gap the encryption task from the transfer task, and even with a court order and a shot gun to their head, the company couldn't give you data away.

          The order could say to covertly insert a backdoor of the NSA's choosing in the "open source" client; or provide the NSA operatives root access to the server that distributes the client binaries, and the keys to push out a new release of the software.

          Someone maintains the code that the users are using. And the maintainers could very easily be subject to a gag order; to not discuss the covert backdoor, even if it's visible in the open source code ----- it doesn't have to be, though: most people will just download the project's (NSA-patched) binary builds of the release.

            When someone is buying a security product, and buying one that specifically bills itself as open source you can bet there will be many many sets of eyes on the code. It only takes one person to spot something like that, and you would be able to add your own layer of encryption on top of what was already in the open source.

            So, no, open source is not as easy to beat as you suggest.

          • It's harder to covertly insert a backdoor into an open source client because people can watch the changes. It's much easier to insert it before it's open sourced, because then people have to review the entire code drop at once. That said, adding a back door into OpenSSL would be comparatively easy because no one understands the convoluted twisty maze of code paths in it.

        The key to fighting the NSA is to provide a completely transparent API.

        And then rely on 3rd parties to deliver software that uses the API.

        Drop "US-based", because the US government has already made use of foreign police (Sweden illegal server raids, New Zealand illegal server raids, extradition of "hackers" from the UK, etc) to shut down foreign sites claimed to be violating US laws. Perhaps it's better to say "No cloud service in a US friendly country can really fight the NSA". So you can always go for storing your data in an UNfriendly country. But since they're unfriendly what makes you think your data would be safer there? Quite the conundrum.

      It's pointless anyway against the NSA. Seriously. Every single modern operating system (including on routers) has tons of unpatched exploit vectors. There's even a black market for them. The NSA can just infect your machines and ex-filtrate your data and/or the encryption keys... See the previous story:

      [NSA] Budget documents say the $652 million project has placed 'covert implants,' sophisticated malware transmitted from far away, in computers, routers and firewalls on tens of thousands of machines every year, with plans to expand those numbers into the millions.

      Hell we have multiple celebrations of insecurity every year called "computer security conferences" where without fail new systems are compromised. How can you even look at stuff like Pwn 2 Own, and not have your brain melting in cognitive dissonance as you try to believe there are network attached scenarios where your data is safe from the NSA?

      You want your data kept secret? Use whole drive encryption on machines that are never connected to any networks -- And even then there's the Ken Thompson Microcode Hack [bell-labs.com], so your systems could be theoretically pre-hacked from the factory... I won't buy a CPU that has remote cellular capabilities... Like Intel's Sandy Bridge [techspot.com]. Laughed my ass off when I heard about that! "Security Feature" indeed. At least if the machine can't get on the networks there's a much lower chance of your data escaping if it's pre-hacked.

      I don't know of any hacker worth their salt -- black, gray or white hat -- that doesn't have a directory of unpatched zero day exploits.
      I keep mine in: ~/with/great/power/comes/great/responsibility/
      Me having to navigate the directory structure has saved many a newb... The NSA has no such sensibilities.
      If the data's encrypted, they assume it could be from a foreigner, and thus give themselves license to get at it, and they can.

In essence, towards devices managed by people that you have a mutual agreement or a true definable trust relationship with.

          I'd like to hear *one* example of a useful application that is better off in "the cloud" than implemented with other schemes, even a bunch of VM's in your own data center. All I can think of are one-off raw-power activities using only publicly available data. And even those could be distributed if you have an adequate web of trust.

          The usefulness is not so much that the cloud is better, but it's much cheaper and much more available for clients with smaller budgets. Having a 200GB backup service for $10 a month, or my own server for $20 a month, with high availability, high speed upload and download. I can't offer that here at home (slow upload, no offsite backup) or elsewhere (much more expensive, more difficult handling the hardware in case of trouble).

    At best the service will simply be shut down by the NSA if they cannot compromise it. Lockbox claims to use client side encryption. If the system is executed perfectly and all of your data is fully encrypted before it leaves your computer this might be difficult, but if the service is shut down you will probably lose your data anyway. Which means you will need a local backup which would seem to ruin the point. I think it's about time to admit that saving any data on a remote server in the US, UK, or close allies of either has to be considered to be stored by the NSA/GCHQ and forwarded to other law enforcement agencies if deemed appropriate. And international cooperation in this regard among close allies cannot be ruled out.

    In the sort of privacy-hostile environment currently faced in the US, UK and much of the world going full tin foil hat is the only way. Any information you want to remain private has to be encrypted by a system fully under your control before it leaves your computer and your passphrase has to not just be secure, but NSA/GCHQ secure. And it wouldn't hurt to toss in some multifactor authentication and steganography as well.

    SpiderOak [wikipedia.org] has had client-only encryption/decryption using 2048-bit RSA & 256-bit AES for its sync/backup/versioning service for years -- I believe ever since they opened in late 2007. That sure sounds like what this newcomer is touting, except that SpiderOak also has free 2GB accounts with live versioning, and uses binary executables on all platforms to do the encryption/decryption (Lockbox uses a Java web client, which I thought was a security no-no).

    FWIW, I don't get jack out of pointing out SpiderOak. I've just been really relieved that it has restored documents that I completely fucked up (live versioning FTW) and think it's seriously overlooked/underrated.

    Seriously. If they want to be taken seriously as offering a service proof against the NSA, they need to not be an American company and to not have any physical US operations. Otherwise a secret FISA order (e.g., issue a client update that sends the encryption keys along with the next batch of data), and their customers are screwed.

    No cloud service (or any other service) in the US can be trusted.

    This is how LastPass.com works. Very good idea and works well but I must trust that future updates are not modified by an "NSA Patch" or some sort of court order.

    One way to somewhat "NSA Proof" it would be to separate the encryption and storage software.

  • I think they underestimate the sheer power of the NSA's cloud. If they decide to sic it on a particular encrypted file, they *will* gain access. We're talking about tens of thousands of servers working to decrypt a file.

    Sure they can't do it for every piece of data they're interested in, but if they want something badly enough, they will decrypt it.

    The root problem, appalling pun gleefully intended, is political, not technical.

    Between unlimited resources and questionable legal tactics, the NSA and other sigint agencies can and will always compel or bribe that which they cannot hack. Software crowbars, legal hammers, and moneybags of grease are everything they need. For every new solution, they will create a new problem.

    The only guaranteed solutions are either the (don't hold your breath) complete abolition these government entities, with no successor remakes, or the courts and Congress must hamstring them with crystal-clear transparency (still possible, but politically unlikely).

    To believe otherwise underestimates the present unfettered powers, technical, legal, and financial, of the government.
