    IIRC, that's been the case since the RIPA was first proposed. If the police come knocking and say "Give us the key", the burden of proof is on you to be able to show that you can't.

    Nah - they first have to show what reasons they have to believe that you have the key. An old bit of ciphertext lying around which is months old would be childsplay for any competent lawyer to show that you couldn't remember the key.

    Failure to give them the key can lead to 3 years in prison.

    Two years. Five in the case of an terrorism related investigation.

    There was also talk of a proposal whereby if you discuss the order to hand over the key with anyone, you can get 5 years in prison.

    S.59 - tipping off offence. But they have to show that the course of the investigation would be compromised if you disclosed that your key was under police control. However, revoking your key is not a violation of S.59. (Just don't revoke it with the reason code of "The rozzers have my key").

    1) You forgot the password. This happens. I deal with many password reset requests a year and this is for computer/e-mail accounts that people use on a regular basis. If these people can't remember that, I find it extremely reasonable to assume they'd forget the password to an encryption volume they don't often use. Well, if you can go to jail for refusing to disclose your key, then you can go to jail for being forgetful.

    So what's the problem? If you can convince a jury that you've forgotten the passphrase, then you're off scot-free. You don't have to convince a judge - you need to convince a jury. This was an appeal to see if the original judge had made an error in law. Hence no jury.

    2) A file that isn't yours. Your computer gets hacked, or someone you know uses it without your permission. Whatever the case, an encrypted file gets stuck on your computer that isn't yours. You can't had over the key, you don't know it. However there's no way to prove that so you go to jail.

    No. You don't have to prove a damn thing. The prosecution has to prove that you do know the key. If there's reasonable doubt, then the charge can't stick. But if there's forensic evidence on the computer that the ciphertext and keyring were accessed when the computer was known to be in your possession, then that could establish such ownership.

    3) Random data. Good crypto is nice and random. You can't distinguish it from other random or pseudo random noise. So you have a random file on your computer, or maybe just random data that there is a deleted file record for (as in there was a legit file there, it got deleted, it's space has now been overwritten by garbage). You can't prove it isn't encrypted data so you go to jail.

    The prosecution needs to prove that it isn't random data.

    Look - let's be clear here. If I see an S/MIME or OpenPGP email in someone's inbox, I'm not going to think "Well, it could just be random data". That's perverse. If someone said that a huge file on a disk is a One Time Pad, and showed software on the computer which makes use of the pad, then that's a reasonable excuse for not decrypting the data.

    The folks in this case probably used PGP or the like. The "it could be random data" excuse just won't fly. They didn't want to produce documents because they were hidden, and the documents might convict them. That's not self-incrimination, it's refusal to obey a court order.

    I have no doubt that if a safe deemed to contain likely evidence could not be opened without destroying the contents, then a court would order the keyholder to open the safe, or risk contempt proceedings upon refusal.

    With things like this in place there is nothing preventing anybody (police/government or over-wise) from creating files of random data (which encrypted data is indecipherable from) that contain nothing, labeling them in alluring way, and as the defendant (whom the files were laid on) cannot come up with encryption keys, putting them in jail.

    Forgive me, but how is this different from the police manufacturing any other sort of evidence? The courts still demand an untainted evidence trail, leading from seizure to production. Unless you're suggesting that the executive, judiciary and police forces are all in collusion to ignore standard jurisprudence?

    In which case, why bother with courts and democracy at all, if we're already in such a corrupt state? You have to have some faith that the court processes are geared towards justice at some level.

    It's not enough to produce a random blob of data - you have to produce ancillary evidence that this blob is an actual enciphered blob. How does the CPS/Procurator Fiscal do that? That's their problem - not the defendant's.

    Now, this isn't enshrined wholly in RIPA - but that's why you can't read statute like code. It's not self contained or referentially complete. All sorts of other information go to make up the balance of judgment.

    No - it's not quite that bad. Yet.

    In order to secure a conviction under S.53, the prosecution has to show several things (beyond reasonable doubt):

    1) That the blob of data on the disk really is an encrypted blob, and not just random data. A file called "entropy.rand" is likely to be viewed differently than one called "cipher.enc".

    2) That the key to that data is in the possession of the suspect, ie. there's a PGP key in his keyring which corresponds to the one used to encrypt the ciphertext

    3) That the suspect could reasonably be said to have access to the key. So, for instance, if the keyring had been accessed in the last two days, "I forgot it" is pretty unlikely to wash. If, on the other hand, it was accessed six months ago, a jury might well be inclined to believe such an excuse.

    And the court order for the key is supposed to be based upon the notion that there is sufficient evidence that the ciphertext is likely to be of interest. So, a cleartext file saying "Jihad targets listed in file cipher.enc", then the coppers probably have reason to believe that file cipher.enc is a legit target. However, if the coppers came across a USB key in someone's car with an encrypted "My Pr0n" folder, then that would possibly be deemed irrelevant. In any case, plaintext production would be far more likely ordered than key handover.

    It would be interesting to note - was plaintext production ordered first, or was key handover? The code of practice says plaintext comes first unless special circumstance obtain.

I suspect not - it'll be held up in committee stage for six months or so, and the Lords for a good few months - so it'll be around election planning time by the time it resurfaces. Strongly suspect a "time has run out" excuse, with a promise to reintroduce it if they get re-elected, which is not very likely. But at least Brown has shown himself to be tough. And that's so much more important than piddling matters like governing the country well.

    Everything about it is gesture politics. Given all the caveats that have been put in place to get the bill through, it's actually just a shadow of the Civil Contingencies Act (which is already law).

    In other words, if a genuine emergency takes place (ie, multiple terrorist outrages), Parliament can be called to grant the police emergency holding power - enabling suspects to be held for up to 58 days.

I would have preferred defences to be spelled out in the primary legislation - since that's as good for the prosecution as the defence. By leaving it to a CoP, it means that the prosecution services now have no clear statutory basis for issuance of notices (and will therefore be reluctant to issue them for fear of challenge); and the defence will certainly be able to delay production of plaintext (because of uncertainty) to the extent that any jury will believe the claim "Well, I probably did know the key at the time, but I've long since forgotten by now. But I couldn't have complied then because I didn't know if it was all kosher").

    Note: I think this whole story is a pile of crap. No RIPA S.49 notice has been served.
