Abstract

The invention discloses a method for interacting signaling safely in a session ignition protocol (SIP) registration domain. The registration authentication process is the challenge-based registration authentication process which is defined in the RFC3261, but a digital certificate of the double-key mechanism is adopted in the registration authentication process, therefore, the bidirectional digital-certificate based authentication mechanism is realized, and a shared key SEED used for the non-registration signaling digital abstract authentication is transmitted safely. The non-registration authentication signaling adopts a convenient and efficient digital abstract authentication mode with strong compatibility so that the secure computing expenditure is very little, and the coexistence of high safety and high performance is realized. The invention can prevent the Impersonation attack, the Bye attack, the Cancel attack, the REFER attack, the UPDATE attack and other typical SIP attacks of the server. The invention utilizes the association of the registration authentication and the non-registration authentication and combines the high safety of the double-key authentication and the high efficiency of the digital abstract authentication, thereby having high utility value.

Description

technical field

[0001] The invention relates to a signaling security interaction method in a SIP registration domain, which belongs to the technical field of communication and video monitoring. technical background

[0002] In recent years, the Session Initiation Protocol (SIP) has received great attention in the field of communication and network research, and it is one of the core protocols of the next generation network. It was originally a standard proposed by the MMUSIC (MultipartyMultimedia Session Control) working group of the IETF to solve the signaling control on the IP network. In the layered model of IP network, SIP is a signaling protocol working on the application layer, which can be used to establish, modify and terminate the multi-party multimedia session process. Because of its simplicity and efficiency, SIP has been widely used in multimedia interaction; however, in the process of formulating the SIP protocol, most of the attention has been placed on how to...
