Abstract:
A sender's encrypted communication apparatus and a recipient's encrypted communication apparatus autonomously generate keys for encryption with respective key generators, store the generated encryption keys in respective encryption key memories, and store part of the generated encryption keys in respective authentication memories. The keys stored in the authentication memories are used for mutual authentication when the sender's encrypted communication apparatus and a recipient's encrypted communication apparatus are connected to each other.
