Neglecting the Lessons of Cypherpunk History 103

Nicola Hahn writes Over the course of the Snowden revelations there have been a number of high profile figures who've praised the merits of encryption as a remedy to the quandary of mass interception. Companies like Google and Apple have been quick to publicize their adoption of cryptographic countermeasures in an effort to maintain quarterly earnings. This marketing campaign has even convinced less credulous onlookers like Glenn Greenwald. For example, in a recent Intercept piece, Greenwald claimed:

"It is well-established that, prior to the Snowden reporting, Silicon Valley companies were secret, eager and vital participants in the growing Surveillance State. Once their role was revealed, and they perceived those disclosures threatening to their future profit-making, they instantly adopted a PR tactic of presenting themselves as Guardians of Privacy. Much of that is simply self-serving re-branding, but some of it, as I described last week, are genuine improvements in the technological means of protecting user privacy, such as the encryption products now being offered by Apple and Google, motivated by the belief that, post-Snowden, parading around as privacy protectors is necessary to stay competitive."

So, while he concedes the role of public relations in the ongoing cyber security push, Greenwald concurrently believes encryption is a "genuine" countermeasure. In other words, what we're seeing is mostly marketing hype... except for the part about strong encryption.

With regard to the promise of encryption as a privacy cure-all, history tells a markedly different story. Guarantees of security through encryption have often proven illusory, a magic act. Seeking refuge in a technical quick fix can be hazardous for a number of reasons.

      A security solution does not have to be 100% perfect to still provide value.

      Let's take another example. A workstation requires pressing Ctrl-Alt-Del and typing a password to unlock the computer. You might say that it is useless protection because an attacker can just walk away with the hard drive of the computer.

      So why is the password still useful? Well, without a password, an attacker might just start locally using the computer and quickly take a look at various secret documents. If he were to grab the hard drive, it would take significantly more time, which would increase the chances of being captured by the security team.

      To get back to the topic, by using encryption you are not the lowest hanging fruit out there.

      There is no indication PGP/GnuPG can be broken if used right (some minimal care needed, e.g. verifying that you have the right keys for the people you communicate with). Things like BitLocker or current Phone encryption do not deserve much trust though.

If Apple and Google cannot break their encryption, then they cannot break their encryption, and no number of NSLs is going to change that. At the same time they cannot be forced to put backdoors into their products as that decreases product quality.

    TFA is correct that simply thinking that, because there is a zillion-bit crypto algorithm thrown into the communication stream, that everything is good and security is guaranteed. There are many, many attack channels that do not involve brute-forcing the crypto. Keyloggers, for example.

    But this is silly:

    Back in the 1980s and 1990s, a group of encryption mavens known as cypherpunks sought to protect individual privacy by making "strong" encryption available to everyone. To this end they successfully spread their tools far and wide such that there were those in the cypherpunk crowd who declared victory. Thanks to Edward Snowden, we know how this story actually turned out. The NSA embarked on a clandestine, industry-spanning, program of mass subversion that weakened protocols and inserted covert backdoors into a myriad of products.

    In actuality, the crypto implementations promoted by cypherpunks were exactly those that made it difficult or impossible for such a program of mass subversion to take place. Remember that the height of the cypherpunk movement was when the Clinton administration was pushing hard, really hard, for the NSA-sponsored Clipper Chip, which was, in a nutshell, crypto subverted by design and mandated by law. We now know that when the spooks found that was politically impossible, they went ahead and did it anyway, in secret. But the cypherpunk tools, most notably PGP (and later GPG, when PGP sold out and went corporate). Hell, even look at /dev/random: when it was revealed that the NSA had actually, and pretty amazingly, undermined hardware random number generators on widely available chips, /dev/random was still just fine, because it treats all sources of entropy as potentially untrustworthy, including the chip.

    The first lesson we should learn from the history of the cypherpunks is that trusting your crypto to a closed product is always, always a bad idea. That was the lesson then, and it is still the lesson now.

    The second lesson is that crypto, like any security, is all about the threat model. In that light, should we reject the widespread adoption of end-to-end crypto in commercial products? Of course not. If Apple and Google implement crypto by default, it will make efforts to dragnet information exponentially harder, even if the crypto is imperfect. This is why the spooks are beating the drum against it: it closes off that one particular threat model, which they have come to rely on. It doesn't close off other kinds of attack, but so what?

    The third lesson is that crypto, by itself, is not a panacea. Nobody ever said it was. The cypherpunk message was not that we can write PGP, declare victory, and walk away. The message was that privacy changes the relationship between the citizen and the state in beneficial ways, and that, in a technological society, we need to embrace technological means of increasing our privacy, in ways that cannot be controlled by the state.

    • The NSA embarked on a clandestine, industry-spanning, program of mass subversion that weakened protocols and inserted covert backdoors into a myriad of products.

      Well, you're both right and wrong. What you say is true, but the NSA actually attacked security software, protocols, and even ciphers. They put back doors in some of the tools that people were depending on to defend them from the NSA.

      Remember that the height of the cypherpunk movement was when the Clinton administration was pushing hard, really hard, for the NSA-sponsored Clipper Chip, which was, in a nutshell, crypto subverted by design and mandated by law.

      Sigh. They went ahead and did it anyway, in plain sight. Both intel and AMD have implemented TPMs inside of their CPUs. You can no longer buy a mainstream PC without a TPM.

    • A very good summary. Too many people view crypto as the "Daddy" in their privacy, protecting them from all manner of threats. There are many places where encryption efforts can be compromised, including improper implementation of even well written libraries.

      But to argue, as some have, that it is worthless is wrong as well. It is the moat and wall around your castle. Sure there may be a day when the Mongolians overrun you but at least you have slowed them down by your efforts.

If you've been paying attention, there have been a number cases where a person was ordered to unlock the contents of a laptop or other device under the threat of being put in prison if they refuse. And that is the real problem. If you create some super-duper-encryption that is impossible to break, the various corrupt government agencies will simply declare you to be a terrorist, who can't possibly have any legitimate need for that encryption, and you will be ordered to decrypt or go to prison, and nobody will even know you are in prison thanks to secret laws enforced by secret courts.

    But trying to cripple cryptography this is something we already are aware of, and there are ways to shore up the technology to make it much, much harder for government to spy on us in bulk. Even using weak, crippled cryptography forces the spies to expend computing resources. Cryptography is all about raising the cost of spying, when dealing with government, not with preventing spying.
