ABSTRACT:
A user support system for cryptographic communication includes a key storage for storing keys used for deciphering, a deciphering part for deciphering an enciphered communication text into a deciphered communication text using a key, and a controller for starting the deciphering part only when an input communication text is the enciphered communication text and for supplying the key that is necessary for the deciphering in the deciphering part by retrieving the key from the key storage.
