Thoughts

A day in my life ... sometimes I can't remember where I got it from, sorry.

Alice: History of cryptography is enriched by errors about the own knowledge.

Bob: Ah, you mean, I don't know enough?

Alice: Yes. You're right.

some hours later ...

Malroy: I got your conversation. It's arousing, but totally wrong. You're talking base64 and ascii.

Alice: Yes. You're right. Hey Bob, our telepathy has been broken.

Bob: You mean, somebody got to know our thoughts?

Alice: Yes. You're right. At least, somebody means to have seen them.

Bob: Thats not a problem, we don't think about important secrets.

Alice: Sorry, now you're wrong. Nobody should know, we are thinking at all, really.

Bob: Ok, from 1984 we already know how to hide our thoughts, let's choose a song... We're far behind 1984! They are behind us, and they have learned how to do it best.

Alice: To be paranoid does not mean nobody is behind you.

q.e.d.

This little picture was taken on one of my trips to Munich in the "Deutsches Museum München" from the 4-rotor enigma (marine version). It's one of the best investigated crypto machines in history. Thanks to Alan Turing and Marjan Rejewski.

Major flaw was the lack of randomness. ;-)
