Non-Repudiation in Internet Telephony [PDF]
International Federation for Information Processing, 2007 We present a concept to achieve non-repudiation for natural language conversations over the Internet. The method rests on chained electronic signatures applied to pieces of packet-based, digital, voice communication. It establishes the integrity and authenticity of the bidirectional data stream and its temporal sequence and thus the security context of

Internet protocol support for telephony [PDF]
Proceedings of the IEEE, 2004 In this paper, we consider the evolution of telephone networks from time-division multiplexing circuit switching to packet switching and, in particular, to packet switching-based on Internet Protocol (IP-supported telephony). We analyze IP-supported telephony design solutions by proposing a layered reference model in which each layer is associated to a

On building an Internet gateway for Internet telephony [PDF]
2000 IEEE International Conference on Multimedia and Expo. ICME2000. Proceedings. Latest Advances in the Fast Changing World of Multimedia (Cat. No.00TH8532), 2002 Internet telephony has the potential to significantly reduce the cost of long distance voice communication. Thus, it is very important to construct a PSTN/Internet gateway for further experiments and developments. We explore several methodologies for the implementation of a PSTN/internet gateway.

Internet telephony gateway location [PDF]
Proceedings. IEEE INFOCOM '98, the Conference on Computer Communications. Seventeenth Annual Joint Conference of the IEEE Computer and Communications Societies. Gateway to the 21st Century (Cat. No.98CH36169), 2002 Although the Internet was designed to handle non-real time data traffic, it is being used increasingly to carry voice and video. One important class of contributors to this growth are Internet telephones. Critical to more widespread use of Internet telephony is smooth interoperability with the existing telephone network.
