SIP Security Essay -- Information Technology

diddleThe session initiation protocol (SIP) is emerging as standard protocol for session control in Next generation voice everyplace internet protocol (VoIP) As it is based on IP it is defenceless to all IP related threats . Among all the attacks, flood-based denial of service make attack is one of the main threats to SIP. Several solutions regarding prevention of DoS ar discussed. Efficient Security scheme is proposed for batter performance. I.INTRODUCTION Session outset Protocol (SIP) 1 is signaling protocol given by the Internet engine room Task Force (IETF) for IP telephony. Moreover, the 3rd generation partnership architectural plan (3GPP) has chosen SIP as a signaling protocol in IP multimedia subsystem (IMS). With more and more multimedia applications and the digital sound/video transport over IP-based networks, SIP is becoming the de-facto signaling protocol. In fact, SIP is a session control protocol that can establish, modify, and modify multime dia sessions such as Internet telephone calls (VoIP). SIP users are indicated by Uniform Resource Identifiers (URI), consisting of a pair of user defecate and domain name, e.g. sipaliabc.co.uk , which is similar to the email format.SIP signaling surrounded by multiple users consists of asks and responses .A call is set up in SIP by the three-way handshake composed of INVITE, 200 OK and ACK messages. The INVITE request asks the cal lee to join or establish a call. If the cal lees response indicates that he/she accepts the call by sending the 200 OK response message, the company confirms that it has received the response by sending the ACK message. When the caller or cal lee wishes to terminate a call, they send a strait request. ... ... June 2001.8 T. Peng, C. Leckie, and K.
