| Research Abstract |
We pointed out some problems for "Secure Communication with SIP". Especially, we focused on a problem that we could NOT protect communication from intervention of proxies. Thus we have suggested TWP method that we established a reliable web proxy in a network. Then we can realize secure VoIP communication. Additionally, we also suggested extended TWP method that adapt to large scale networks. Finally, we wrote some papers and had presentations at some symposiums, and we have returned benefits from this grant to society.
