ABSTRACT:
A cipher-key distribution system used in a one-way communication from a first party to a second party. The cipher-key distribution system is composed of a first subsystem, a second subsystem, and a common file which stores information publically accessible by the first and second subsystems. The first subsystem generates a cipher-key based on a constant, receiving party identifying information, a random number, and public information from the common file. The first subsystem also generates a key distributing code based on a constant, a random number and a first secret information and transfers the key distributing code to a second subsystem. The second subsystem receives the key distributing code and information for identifying the first party and generates a second cipher-key identical to the cipher-key generated by the first subsystem. The second cipher-key is created from the information for identifying the first party, a second secret information, and the key distributing code. The first subsystem, instead of generating and transmitting a key distributing code, may simply transmit information for identifying the first communicating party to the second subsystem.
