| Abstract(in English) | In the VoIP (Voice over Internet Protocol) communication using a public network, there is danger from which the content of the telephone call is tapped by a malicious third party. Therefore, there is VoIP over SSL (VoIPs) that encrypts the content of the telephone call and communicates. However, VoIPs cannot keep hiding the content of the telephone call after the code key is tapped once, consequence of using the same code key in the VoIPs communication. Moreover, it is difficult to apply it to low processing terminal, because the calculation cost would rise when the code key is regularly renewed. In this study, the SAS-2 authentic method was applied to the renewal of the code key, and the proposal and mounting and the evaluation of the communication protocol that achieves a low-cost key exchange were done. |
