IPC: H04L9/08
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To improve communication processing speed in ciphering communication by transmitting common keys to communication equipments belonging to a group where the equipments mutually make communication to the communication equipment belonging to the group. SOLUTION: The plural communication equipments 110 which mutually make communication are previously grouped and are stored in a communication equipment group storage means 101. A data ciphering key generation means 102 generates the data ciphering key. A data ciphering key transmission means 103 transmits the data ciphering keys to the respective communication equipments 110 stored in the communication equipment group storage means 101. Thus, the common data ciphering keys are simultaneously transmitted to the plural communication equipments 110 which mutually make communication. In the communication equipment 110 having received the data ciphering key, a ciphering processing means 111 ciphers or decodes communication data 112 by using the data ciphering key.  The ciphered communication data is transmitted/received with the other communication equipment 10 by a transmission/reception means 113.
