Improvement of a SIP Security Mechanism

Abstract:

SIP is one of the mainstream protocols in the VoIP. A majority of SIP’s security mechanism only provides a single direction authentication from server to client such as HTTP digest authentication. To improve the present situation, a new security mechanism of SIP based on the improved HTTP digest authentication is put forward in this study. This improved security mechanism not only provides a double direction authentication between the server and client but also reduces the expenses of the server and increases the authentication efficiency thanks to its low computational complexity.
