  Are current ciphers even simple enough for something like that? RC4 is pretty trivial to implement, but I think of AES as being pretty complex.
  - ryan-c 12y ago
    Part of the point of CipherSaber was that not only is RC4 trivial to implement, but it is feasible to do so entirely from memory. I can't think of any other cipher that comes close to that except for maybe XXTEA (and it's progenitors, TEA and XTEA). RC4 is so trivial that several people (including myself) were able to write implementations that fit in a single tweet.
  - api 12y ago
    Salsa20 / ChaCha is pretty simple. Curve25519 is not exactly simple but it's pretty small -- small enough to put on a shirt.
  - rsync 12y ago
    All you need is a hashing algorithm (something like md5, but not md5, of course). If you can memorize a hashing algorithm, then you can use the hash to verify larger pieces of software that you can't memorize. So large, complex crypto doesn't ever need to be memorized - all you need is an easy to memorize hashing algorithm.
- ryan-c 12y ago
  I wonder how a variant of XXTEA (perhaps with more rounds) would fare as a replacement. It's only a little more complicated to implement than RC4, but solves some of the issues. It acts as a wide block cipher which reduces the impact of not having authentication or IVs.

The difference is that most devices are now running strictly proprietary software. The crypto war and the "war on general purpose computing" mean that privacy is being attacked from two fronts, not just one. In the '90s, you could distribute code for PGP in a book, and effectively circumvent regulation. Now, you can ban encryption apps in the walled garden and effectively shut down an entire genre of computation.
- jonawesomegreen 12y ago
  This. I was coming here to write this post. Walled gardens also mean that it is difficult to ensure you are actually using crypto with no backdoor, versus the appearance of using crypto.
- zxcvcxz 12y ago
  How can you tell when a closed source application is really secure? Is there a way to be 100% sure or does it always rely on a certain amount of trust in the developers/distributors? Sorry if it seems like a dumb question..
  - api 12y ago
    You can't, at least not practically. You could do debug/trace analysis and reverse engineer but that'd be a massive undertaking. But it's also quite hard to tell if an open source application is secure. Do you have time to audit thousands of lines of impenetrable C/C++/Java/Go/etc. code? The rash of OpenSSL bugs we've had recently shows that "Linus's law" really doesn't work -- the fact that the code can be audited openly doesn't mean anyone is going to spend the time to actually do it. People are busy. It comes down to the question of "how paranoid are you?" If I were highly paranoid I'd take a defense in depth strategy -- layer multiple cryptosystems, possibly on multiple OSes/platforms, etc. But that level of paranoia comes at a price of course, both in setup time and overhead. iMessage is pretty good for every day use. PGP is probably better since you have greater transparency, but is less convenient. SSH and SSL are also pretty good for every day use. But I would trust none of those things to protect me from the NSA or a very well funded criminal adversary.

I've created a little series of lessons to teach our Year 8 (12yo) students about cryptography, as a direct response to all this rubbish. https://bournetocode.com/projects/8-CS-Cryptography/ https://bournetocode.com/projects/8-CS-Cryptography/ If there is a second crypto war, I want my students to have a little bit of a head start.

> If you’re using an up-to-date iPhone to send a text message to another iPhone user, and the little bubble containing your message is blue, then neither Apple, nor your ISP, nor any law enforcement agency tapping into the transmission line is likely able to read the contents of the message. That is incorrect and dangerous advice to give users. As has been discussed before, as long as Apple controls the public key exchange process, they have the capability to intercept and decrypt your messages if they wish, or are compelled to do so.
- nnutter 12y ago
  What advice could one give that wasn't dangerous?
  - UVB-76 12y ago
    Assume that everything you send via iMessage can be intercepted [1] [1] At least by an adversary with sufficient resources, leverage, and impunity (NSA, GCHQ, etc.)

    - SoftwareMaven 12y ago
      Nobody has something that would fulfill your caveat, with the possible exception of a few larger countries. If you are the named target of the NSA, they will find a way into your communications. This war really has little to do with find the way into a named person's communications; it has much more to do with finding the names of people whose communications they want to see. For that, iMessage is devastating (assuming it is implemented and behaves as marketed, a pretty big assumption).
      - TillE 12y ago
        > If you are the named target of the NSA, they will find a way into your communications. This is completely false. Use good cryptography properly, and make sure your system isn't hackable. PGP + Tails is a popular combination for Glenn Greenwald and others like him.
IshKebab 12y ago
Despite what Apple say, they can read their messages. The NSA could get a secret court order that says "Please silently disable encryption for user Dave Jones in your next software update and forward his messages to us. Tell no-one." I don't see how Apple could avoid that - the government already uses secret legal means to make them do things they don't want to and prevent them from telling anyone. This is no different.

BTW, the infamous 40-bit limit was set as part of a deal between NSA ans SPA in 1992, and applied to the RC2 and RC4 algoritms.

    I am talking about what was guaranteed to be exportable under the "7-day" review process, though 40-bit was a good rule of thumb for other algorithms.
p01926 12y ago
While certainly not a magic bullet, zero-knowledge systems are our best last line of defence against zero-day exploits. As the author is the CEO of the company that issued the infamous "Heartbleed Challenge", he should acknowledge that far from being some war of geeks vs spies, it's geeks vs malicious hackers. Yes, as far as Google's concerned, GCHQ fits that description, but it's silly to claim it's just about them. Even if you consider some intelligence agencies benign, there are a hundred-fold more that definitely aren't. And the only underestimation happening here is the politicians'. If the cryptopocalypse were to happen tomorrow (i.e. David Cameron's fantasy), modernity would end as we know it. Financial markets wouldn't so much collapse as cease to exist. Hungarians recently took to the streets over a tax on data; what would happen if e-commerce became impossible? Imagine the impact on the rule of law if 10% of the economy disappeared overnight. Encryption isn't a threat to LE, it's the only thing protecting them from a nightmare.

The crypto war is not being waged by apple or google, that is ridiculous!
ewzimm 12y ago
The first sentence sums up what's wrong with government reactions to crypto. >[...] for the first time in history, anyone could encode and exchange a message that no law enforcement agency had the technical ability to intercept and decode. Here's one famous counterexample: https://en.wikipedia.org/wiki/One-time_pad https://en.wikipedia.org/wiki/One-time_pad People have always been able to communicate secrets. I don't underestimate the value of doing it conveniently, and obviously many people have been caught by lazily talking on a wiretapped phone, but the crypto war is only a war on convenience. There can't possibly be an effective war on communicating secrets unless people just give up trying. If governments want to fight it, they should at least be honest and say they're fighting convenient crypto, not crypto in general. They're fighting crypto that average people can access easily, crypto that makes everyday privacy achievable, not crypto used by coordinated criminals. At least it would make more sense and could lead to a reasonable debate.
- lukifer 12y ago
  Given the "code == speech" SCOTUS ruling, they may not be able to outlaw crypto tech itself, but they can damn sure throw you in a cage for using it, based on ISP monitoring and mandatory key disclosure. As with guns, the criminals will simply ignore the law. Anti-crypto legislation will be aimed squarely at We The People.
  - ewzimm 12y ago
    I agree, but I also think if that happens, crypto will adapt to things like custom protocols built to be indistinguishable from regular traffic. The great thing about code is that there's usually a way to change the rules. The scary part is that it leads to an endless arms race.
    - crpatino 12y ago
      > crypto will adapt to things like custom protocols built to be indistinguishable from regular traffic. The name is steganography, and has been used since ancient times. The best way to ensure the secrecy of a message is to prevent the adversary from learning the existence of the message. Second best is to provide a bunch of big dumb decoys for the real message to hide.

  They are very clear and upfront about it and there are many cases where their simplest offering (the one with no encryption behind edge server) is good enough.
  - lawl 12y ago
    except the one with selfsigned certs doesn't really make a difference, and even for the last one as far as i know they still decrypt and recrypt stuff with their own key to be able to do caching etc. Meaning, it's still not end to end, which is what you would expect when you hear SSL. Where are they upfront about that?
guard-of-terra 12y ago
This time we should not fear of loud laws, but of silent subversion. You can no longer tell good guys from bad; everyone you trust can betray you. Forced to make pacts with bad people, giving them everything of yours.
w8rbt 12y ago
When everything on the wire uses strong crypto, the only useful network data will be metadata. It will be interesting to see how traditional network IDS/IPS evolve to handle this. The signatures will be useless when they can't parse plaintext packets. Of course, orgs can always attempt to terminate SSL and do things with the cleartext packets, but that can get dicey. Strong encryption on the wire (in transit) also renews the focus on the end points. The data are plaintext in memory on the devices. If the end points can be compromised, the data access problem is solved. Lot's of people are writing exploits (both good and bad guys) to do that. When you combine network metadata with local device data, you've got a pretty complete picture.
- mirimir 12y ago
  Right. End-to-end encryption is just one of three key aspects. The second is hiding or randomizing metadata. Old-school Mixmaster nyms with Tor transport and alt.anonymous.messages as inbox does a good job. It's fatal weaknesses are complexity, and consequently small anonymity space. Services such as CounterMail, Tutanota and ProtonMail are taking user-friendly (abeit weaker and proprietary) approaches. DarkMail may eventually be a fundamental solution, but may be too ambitious. The third is end-point security. It's crucial to use full-disk encryption, and to avoid being exploited. That involves both software and wetware hardening. But even that's inadequate. It's essential to compartmentalize unconformable information in separate and isolated compartments. Isolation comprises all aspects: devices, network and Internet connectivity, communication partners, and so on.
  - unsignedint 12y ago
    I like to also add an anonymous recipient feature present in OpenPGP. (-R or --throw-keyid for GnuPG) to strip metadata. (Supported at least on GnuPG for encryption/decryption, and Mac version of PGP for decryption. For some reason, not on Windows.) Also, implementations like GnuPG will allow recipient ID to be spoofed, but even less implementation will support it. I believe using this in conjunction with some garbage recipients (with a secret key thrown out immediately after the creation of a public key) will randomize metadata quite well for OpenPGP. EDIT: clarified option switch is for GnuPG

wahsd 12y ago
I don't quite understand how the government thinks this will go. How do they think they are going to prevent encryption? Also, does anyone else realize that they are essentially expecting to have no limitations? They want to, not only be able to essentially have access to your person at any time ... which is understandable to a certain extent ... under authority of a legal and proper warrant; but they now also want to be able to monitor and track every single thing you do and are at all times for future recall. Essentially, they are wanting to be able to reference the experience of your life, approaching your memory. So what stops the government from reading your memories, once that technology is fine tuned? We are seriously on a precipice here, because humanity's political and civil society has not caught up to the exponential advances in technology. The last time such a mismatch existed it resulted in WWI and WWII. Before we emerged, mumbling .... "WTF, just happened"
srj 12y ago
I feel this is the largest threat to freedom in the US in a long time, possibly ever. If the US has the ability to decrypt traffic from all of the major players I think, based on their history, they'll likely try to collect everything. All emails, purchases, internet searches, and so on would be cataloged. For example, if I applied for a government job in the future I could have my allegiance called into question for writing this comment. They would easily know who all but the most vigilant are based on information provided during purchases, correlated with IP addresses and cookie information. The real criminals of course would use any number of other systems (say those based in other countries) which would not be collected in the dragnet. It would only be the average citizen who suffers.
- lbarrett 12y ago
  Yeah. The irony I see in all of this is that the government did this to themselves. Government overcollection of information led to public need for encryption, which in turn led to the fact that the government can't collect information when it does have a legal mandate to do it. The best answer here is: the government should obey the laws and not spy on citizens, and maybe then the citizens won't seek refuge.
