ABSTRACT:
A authentic public key of the other party of user in communications is generated using the other party's user information and identification information, and a center's public information. The center doesn't know the user's secret keys, and no secret communication paths are required between the center and the users. The workload of the users is not increased even if a plurality of centers are introduced to prevent possible wrongdoing by the center.
