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...
today, optimal performance and cost advantages of using internet telephony are obvious. despite current standardized techniques, voice transferring through protocol (voip) has lower security than traditional telephony. one of the most important security issues which should be noticed in using voip is end -to-end user2 identity, i.e. when there is a connection between user a and b, user a shoul...
increasing the popularity of sip based services (voip, iptv, ims infrastructure) lead to concerns about its security. the main signaling protocol of next generation networks and voip systems is session initiation protocol (sip). inherent vulnerabilities of sip, misconfiguration of its related components and also its implementation deficiencies cause some security concerns in sip based infra...
The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying and terminating sessions with one or more participants. These sessions include Internet multimedia conferences, Internet telephone calls and multimedia distribution. Members in a session can communicate via multicast or via a mesh of unicast relations, or a combination of these. SI...
Session Initiation Protocol (SIP) is a new and emerging protocol that is used to establish and release the connmsction between two end systems. It is used in preference to the older H323 protocol. Both protocols provide a similar set of services hut SIP is much simpler because it has less logical components. This paper describes the implementation of a VoIP applicationusing SIP as the handshaki...
Session Initiation Protocol, SIP, provides controlplane signaling for the IP networks. SIP enables initiating, modifying and terminating sessions for a user, while maintaining neutrality to physical media capabilities and using other protocols to negotiate these. SIP assumes that the transport layer is inherently unreliable and as such provides transport layer mechanisms. For target device disc...
The authenticated key agreement protocol is an important security protocol for the session initiation protocol, which allows the and the server to authenticate each other and generate a shared session key for privacy, integrity, and non-repudiation in their communications. Recently, Zhang et al. proposed a new authenticated key agreement protocol for the session initiation protocol using smart ...
