Abstract

The art and science of cryptography consists of two worlds. There is the world of legal communications: parties such as legal users of a data bank exchanging messages. This world can be viewed as open and sunlit. There is also the dark world of the enemy who illegally tries to intercept the messages and do all kinds of vicious things. For people in the legal world, it is desirable that the enemy understands very little of the messages. The enemy, on the other hand, would like to have easily understandable messages.
