Abstract
In a client-server distributed system including an SIP-protocol-coping server apparatus and an SIP-protocol-coping client apparatus, client authentication of the SIP-protocol-coping client apparatus is performed from the SIP-protocol-coping server apparatus by a client authentication unit. In the client-server distributed system, in addition to the client authentication, server authentication of the SIP-protocol-coping server apparatus is performed by a server authentication unit from the SIP-protocol-coping client apparatus. In the client-server distributed system, authentication completion is recognized when the bidirectional authentication is achieved.
