Patent JP-H11196081-A (JP)
Title: Cipher communication equipment
Inventor: ANZAI JUN
IPC: H04L9/08
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To delivery an updated key which is simple in security in the cipher communication equipment where a common (secret) key block cipher is applied to cipher communication and cipher key delivery. SOLUTION: When a key is updated, a transmission station uses a spare key as a new cipher key, a spare key generated by a generating means 15 is used as a new spare key, the spare key is ciphered by the cipher key and transmitted, then transmission data are ciphered by the cipher key and the result is transmitted. In a reception station, the spare key is used as a new decoding key, the received ciphering key is decoded as a new spare key, and then the received ciphered data are decoded. The same key is used for the cipher communication and key delivery in prescribed security by always preparing the spare key to be updated periodically. Since the key to be used for key delivery is always unused, security is high and the labor and time for managing the delivery key (generation and update) is omitted. Furthermore, it is not required to decide previously a timing of updating the key between the transmission station and the reception station by deciding the timing of updating the key, depending on the spare key and a plain text and the timing of updating the key is at random, then information for facilitating decoding is hardly specified by a wiretapper.
