Mitigating Mimicry Attacks Against the Session Initiation Protocol

IEEE Transactions on Network and Service Management, 2015
The U.S. National Academies of Science's Board on Science, Technology and Economic Policy estimates that the Internet and voice-over-IP (VoIP) communications infrastructure generates 10% of U.S. economic growth. As market forces move increasingly towards Internet and VoIP communications, there is proportional increase in telephony denial of service ...

A lightweight authentication scheme for Session Initiation Protocol

2008 International Conference on Communications, Circuits and Systems, 2008
Session initiation protocol (SIP), due to its simple architecture and well-defined content, is currently considered the premier signaling protocol for next generation networks (NGN). However, its simplicity will lead to serious security challenges in terms of privacy and integrity.

Multiplayer networked gaming with the session initiation protocol

Computer Networks, 2005
With a strong push from commercial ventures like Microsoft Xbox® and Sony Playstation®, the multiplayer networked gaming industry continues to grow steadily. Multiplayer games allow geographically dispersed players to participate in a single game and in order to provide interaction amongst players in such environments, text messaging and real-time ...

Survey of security vulnerabilities in session initiation protocol

IEEE Communications Surveys & Tutorials, 2006
The open architecture of the Internet and the use of open standards like Session Initiation Protocol (SIP) constitute the provisioning of services (e.g., Internet telephony, instant messaging, presence, etc.) vulnerable to known Internet attacks, while at the same time introducing new security problems based on these standards that cannot been tackled ...

The Session Initiation Protocol (SIP): An Evolutionary Study

Journal of Communications, 2012
The Session Initiation Protocol (SIP) was devel- oped to control multi-media sessions on the Internet. Shortly after its debut as a standard in 1999, SIP was adopted by the 3rd Generation Partnership Project (3GPP) as the preferred signaling protocol for the Internet Multimedia Subsystem (IMS).

The Session Initiation Protocol: Internet-centric signaling

IEEE Communications Magazine, 2000
The Session Initiation Protocol (SIP) provides advanced signaling and control functionality for a wide variety of multimedia services. SIP can efficiently and scalably locate resources based on a location-independent name and then negotiate session characteristics.

A New Authentication Scheme for Session Initiation Protocol

2009 International Conference on Complex, Intelligent and Software Intensive Systems, 2009
In 2008, Tsai proposed an efficient nonce-based authentication scheme for Session Initiation Protocol (SIP). The current paper, however,demonstrates that Tsai's authentication scheme is still vulnerable to off-line password guessing attacks, Denning-Sacco attack and stolen-verifier attacks, and does not provide perfect forward secrecy.

Self-Protecting Session Initiation Protocol Stack

2008
We present the Self-Protecting Session Initiation Protocol Stack capable of recognizing malicious SIP messages and protecting itself in high-load conditions. The stack model is based on the two-step processing and uses hash lookup tables and cellular automata rules to identify SIP message either as a regular or malicious one.

A Technique to Analyse Session Initiation Protocol Traffic

11th International Conference on Parallel and Distributed Systems (ICPADS'05), 2006
The session initiation protocol (SIP) will provide the signaling network in the next generation networks, such as UMTS and cdma2000. Here we study the traffic load generated by the use of this protocol from a methodological point of view. We propose an analytical technique to simulate SIP finite state machine (FSM) in an IP network by means of the ...

Session initiation protocol: Service residency and resiliency

Bell Labs Technical Journal, 2003
As the session initiation protocol (SIP) gets deployed, attention invariably needs to be paid to which SIP entities, user agents (UAs), proxies, back-to-back UAs (B2BUA), host services, and to what the impact is on the entity if the service causes it to fail. This paper discusses providing SIP services in terms of individual entities.
