Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Besides, most people aren't going to find it easy to remember a 256k key, unless it's stored as a passphrase.

The UK has legislation that allows the police to jail anyone who doesn't supply keys on demand. But if you're really serious about security you can use advanced crypto to hide the fact that you have things to hide.

While the NSA might not be fooled, the local plod may well be.

They don't have to remember it. Just build a public key encryption scheme into the phone, and assign it (or the SIM card) a random key from the factory. It shouldn't be possible to compromise that without hardware access (and if they have hardware access then you are, as a rule, pretty much fucked anyway). The secret police will probably insist that the keys are stored so they can be made available on demand, but that should still keep most governments and the lion's share of corporations out of your phone.

their conversations could still have been over-heard if enough time, energy, and money had been thrown at the problem.
