There is an easy way to develop a secret key in front any number of eves, be they experts or not, without the eves knowing what the key is. Even if they tap your phone/comm line, ect. There was an article in Discovery Magazine a couple of years ago, talking about how to use photons and their randomness as the perfect, uncrackable code. Use of the photons aside, there was a key generation method discussed, simple, yet secure enough to work out on a tapped phone. Let me root around.
