The Session Initiation Protocol (SIP) is a text-based protocol for initiating and managing communication sessions. The protocol can be compressed by using Signaling Compression (SigComp). Similarly, the Session Description Protocol (SDP) is a text-based protocol intended for describing multimedia sessions for the purposes of session announcement, session invitation, and other forms of multimedi...

The session initiation protocol is one the most popular protocols that is used in Internet protocol multimedia subsystems and adopted by a wide range of networking vendors. This research suggests a secure distributed session initiation protocol-based architectural model that can be deployed in service provider data centers to maintain the service availability, scalability, and security. This re...

Today, the efficiency and security of session initiation protocol is becoming more and more important. In 2005, Yang et al. proposed a secure authentication scheme for session initiation protocol. However, it is not suitable for the limited computation capacities of users such as smart cards or mobile units. To guarantee the quality of the growing communication services, we propose an efficient...

There is a need for having a globally unique session identifier for the same SIP session that can be consistently maintained across SIP Proxies, Back-to-Back User Agents (B2BUAs), and other SIP middleboxes, for the purpose of troubleshooting. This document proposes a new SIP header to carry such a value: Session-ID. The mechanism defined in this document has been widely deployed, and is being f...

In recent years, Session Initiation Protocol (SIP) has become widely used in current internet protocols. It is a text-based protocol much like Hyper Text Transport Protocol (HTTP) and Simple Mail Transport Protocol (SMTP). SIP is a strong enough signaling protocol on the internet for establishing, maintaining, and terminating session. In this paper the areas of security and attacks in SIP are d...
