SVSP (Secure Voice over IP Simple Protocol) une solution pour la sécurisation de la voix sur IP

Abstract : Since the invention of the first telephone by Alexander Graham Bell in 1869, network telephony technology did not stop evolving: from circuit switching to packet switching, from fixed network to wireless network. Several new architectures were created which combines the transport of voice, data and image in the same data network. The nature of these open networks has an impact on the voice in terms of security. This yields to the imminent need to secure voice communications while insuring a good quality of service to the voice as well in fixed, wireless and IP networks. Different security solutions are proposed for the data. But partial even incomplete solutions are proposed for the voice. First, we define the needs for securing the telephony and the security services required. Thus, we analyze the security offered by the different telephone networks, namely the security in the traditional telephone network (PSTN and ISDN), in the mobile networks (GSM and UMTS), and in the IP network based on the H.323 and SIP architectures. This will allow us to compare the security solutions offered by these telephony architectures and to be able to present their advantages and limitations and the security requirements that they cannot satisfy. This analysis drives us to an eloquent result that is the absence of a complete end to end security solution that complies with the security requirements of telephony. Secondly, we propose security architecture for a unified telephony architecture. This security architecture proposes a service layer that is inserted between N and N + 1 layers of the OSI reference model.
