Securing the Media Stream Inside VoIP SIP Based Sessions
نویسنده
چکیده
One of the main issues encountered in the development of VoIP applications and infrastructures relates with ensuring the security of the communication channel between peers. The discussion on this subject can be split in two principal directions: the signaling path security and the media path security. In this document we focus on the latter by overviewing the current most important available mechanisms and their way of interworking for architectures based on one of the most deployed standards in VoIP communication – Session Initiaton Protocol (SIP).

Security testing of session initiation protocol implementations
The mechanisms which enable the vast majority of computer attacks are based on design and programming errors in networked applications. The growing use of voice over IP (VOIP) phone technology makes these phone applications potential targets. We present a tool to perform security testing of VOIP applications to identify security vulnerabilities which can be exploited by an attacker. Session Ini...
متن کاملAnalysis and Modeling of VoIP Servers: A Linear Programming Approach
The SIP protocol was standardized by the IETF at the application layer for initiating, managing, and terminating multimedia sessions and has been widely used as the main signaling protocol on both the Internet and VoIP networks. Most challenges in this protocol are overload and lack of proper state distribution. These challenges cause a wide range of next-generation network users to face a shar...
متن کاملSecurity and Non-Repudiation for Voice-Over-IP Conversations
This thesis presents a concept to achieve non-repudiation for natural language conversations by electronically signing continuous, packet-based, digital voice communication (VoIP). Signing a VoIP-based conversation means to protect the integrity and authenticity of the bidirectional data stream and its temporal sequence which together establish the security context of the communication. The sol...
