Committee lessons learnt hmm
In the 40s this country was aware of cryptographic systems, we built machines to decipher the ciphers for which we had no key. In the 50s we became even more involved in crypographic systems and (as the story i was told goes) a young 21 year old mathematician working for GCHQ/MI5 finally solved the key management problem. Which was, that for all our data was secure, two separate journeys had to be made, the first transported the key, the second the data itself.
When MI5 implemented what has since become the RSA algorithm (yes that's right you americans it wasn't Rivest Shamir Aldeman that developed RSA first, we did and kept it secret until the release of files in 2001/2, so ner ner) the problem of data security became non-existent.
So why, after our triumphant history of keeping things secret do we still seem to have issues with the transportation of data? when security is as simple as;
C = M ^ e mod N
There was a time that you would be proud to be british with our amazing british thinking (see Al Murray: http://youtube.com/watch?v=o4vPPBRyHew) we were ahead of the game for so long. Now our civil service is full of chimps trying to drive a car.
