Abstract
In a communicator in a communication system, a commission information generator for generating a commission parameter to make a process on a communication between communicators performed by another computer includes a first memory for storing a secret key and an encrypter for generating N number of the commission parameters, where N is a natural number, from a first to an N-th commission parameter. The encrypter regards a j-th shared key, where j is a positive integer equal to or less than N, out of the N number of shared keys as key information, encrypts a bit sequence representation of j-th partial information, associated with the j-th shared key, out of N pieces of partial information, and thereby generates a j-th commissioned parameter.
