IPC: G06F21/31
Filed: 1991-04-26
Abstract: PURPOSE:To obtain a technique which can certify the justification of a message which is received by an arbitrary person and can certify the justification of the transmission source of the received message in a communication network system which is utilized by unspecified and multiple registers through the use of an IC card having a ciphering function. CONSTITUTION:At the time of transmitting the message, one's name is signed to the transmitted message by using individual keys peculiar to the IC cards 11 and 15, and a cipher function, and the message with an electric signature is transmitted to a communication opposite party with ID information. At the time of receiving the message, the individual key of the transmission source of the message is generated from a parameter for individual key generation and transmitted ID information, and the message with the signature is certified by using the individual key and the cipher function. Thus, the forgery and forge of the message and illegal impersonation by a third person can be prevented.
