초록 ▼

An encryption/description apparatus enables encrypted communication between two stations each incorporating such an apparatus. The apparatus is arranged when acting as sender to create (at 71) a mutual primitive from stored items of data, to generate a random session key and encrypt the random session key (at 73) in accordance with the mutual primitive for transmission of the encrypted session key to the recipient station. The sender apparatus further encrypts the main message (at 72) in accordance with the random session key for transmission of the encrypted message to the recipient station. The sender apparatus also stores a registration code and transmits this to the recipient station, where it is decoded (at 74) to recreate the mutual primitive from items of data stored at the recipient station. The recipient apparatus decrypts the encrypted session key (at 75), using the recreated mutual primitive, and then decrypts the main message (at 76) using the recreated random session key.

대표청구항 ▼

[ I claim:] [1.] An encryption/decryption apparatus to enable encrypted communication between two stations, each operable as a sender and a recipient and each incorporating such an apparatus, said apparatus being operable in both registration mode and in encrypted communication mode, said apparatus comprising:a) memory means for storing a first set of data items which include first secret data items and also storing a second set of data items which include second secret data items;b) means for entering a pre-agreed key into said encryption/decryption apparatus;c) means for sender registration including means for creating a mutual code from said first set of data items, means for encrypting said mutual code using said pre-agreed key to form a transfer key, and means for transmitting said transfer key to a recipient, said means for sender registration operable when said apparatus is acting as sender in registration mode;d) means for recipient registration including means for decrypting a received said transfer key using said pre-agreed key to recreate said mutual code, means for deriving a further key from said second set of data items, means for encrypting said recreated mutual code in accordance with said further key to thereby create a registration code, and means for transmitting said registration code to a sender, said means for recipient registration operable when said apparatus is acting as recipient in registration mode;e) means for receiving and storing said registration code from the recipient, said means for receiving and storing operable when said apparatus is acting as sender in registration mode;f) means for sender communication including means for recreating said mutual code from said first set of data items, means for generating a random session key, means for encrypting said random session key in accordance with said mutual code, means for transmitting said encrypted random session key and said registration code to the recipient, and means for encrypting a main message in accordance with said random session key and transmitting said encrypted main message to the recipient, said means for sender communication operable when said apparatus is acting in encrypted communication mode as sender to the recipient with which registration has been made; andg) means for recipient communication including means for decrypting said registration code received from the sender using said second set of data items to thereby recreate said mutual code, means for decrypting said encrypted random session key received from the sender using said recreated mutual code, and means for decrypting said encrypted main message received from the sender using said decrypted random session key, said means for recipient communication operable when said apparatus is acting as recipient in encrypted communication mode.
