The 3rd-Generation Partnership Project (3GPP) has selected Session Initiation Protocol (SIP) as the session establishment protocol for the 3GPP IP Multimedia Core Network Subsystem (IMS). IMS is part of Release 5 of the 3GPP specifications. Although SIP is a protocol that fulfills most of the requirements for establishing a session in an IP network, SIP has never been evaluated against the spec...

Recently, Zhang et al. proposed a password-based authenticated key agreement for session initiation protocol (Int J Commun Syst 2013, doi:10.1002/dac.2499). They claimed that their protocol is secure against known security attacks. However, in this paper, we indicate that the protocol by Zhang et al. is vulnerable to impersonation attack whereby an active adversary without knowing the user’s pa...

Session Initiation Protocol (SIP) Authenticated Identity Body (AIB) Format Status of this Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distri...

Real-time communication has witnessed a dramatic increase in recent years user daily usage. In this domain, Session Initiation Protocol (SIP) is well-known protocol found to provide trusted services (voice or video) end users along with efficiency, scalability, and interoperability. Just like other Internet technology, SIP stores its related data databases predefined structure. recent, technolo...

Session Initiation Protocol (SIP) is widely used for establishing multimedia sessions, and chosen as the signaling protocol in the 3GPP standards. It also attracts many attempts to deploy SIP in a Mobile Ad-hoc Network (MANET). However, traditional SIP end points rely on SIP servers to discover one another and exchange SIP messages, which becomes a challenge due to lack of such server-based com...

This document provides clarifications and guidelines concerning the use of the SIPS URI scheme in the Session Initiation Protocol (SIP). It also makes normative changes to SIP.

This document specifies how to use the Session Initiation Protocol (SIP) to establish a Secure Real-time Transport Protocol (SRTP) security context using the Datagram Transport Layer Security (DTLS) protocol. It describes a mechanism of transporting a fingerprint attribute in the Session Description Protocol (SDP) that identifies the key that will be presented during the DTLS handshake. The key...

Session Initiation Protocol (SIP) is an application layer protocol responsible for creating, modifying, and terminating a session. It is used to establish calls through networks via IP protocol. Nowadays, SIP has been used by many embedded systems, however, due to its large size, some constrained systems cannot use it. This paper aims at adapting the protocol to be used in resource-constrained ...
