As the core infrastructure of the VoIP, IMS and IPTV, SIP based network is now increasingly been deployed throughout the world. Due mainly to the relatively high flow rate and the exorbitant session maintenance, SIP servers are similarly susceptible to the Denial-of-Service (DoS) Attacks above the IP stack, especially when the Distributed spoofing URI is considered. A hybrid SIP DoS detection method...
The stream control transmission protocol (SCTP) uses a cookie mechanism to tackle the security and traditional attack scenario. Unfortunately, SCTP is not secured against redirection attacks, bombing attacks and towards verification-tag guessing attacks which lead to association-hijacking and may force the victim client to starve out of service from the server. Therefore, we propose a secure SCTP...
There is a growing interest in designing high-speed network devices to process packet at flow level above the network layer. A basic operation inherent to such systems is the task of maintaining per-flow state in order to correctly perform their higher-level processing. In this paper, we present an efficient TCP flow state management algorithm in high-speed network. First we devise all flow states...
IP multimedia subsystem (IMS) is a new next generation networking architecture that will provide better quality of service, charging infrastructure and security. The basic idea behind IMS is convergence; providing a single interface to different traditional or modern networking architectures allowing better working environment for the end users. IMS is still not commercially adopted and used but research...
