Abstract :
In today´s era VoIP system is globally accepted and popular communication system because of its rich features. VoIP system uses two signalling protocol: H323 and SIP (Session Initiation Protocol) for session initialization. Out of these SIP is popular amongst VoIP subscriber because of its light weight nature. SIP is vulnerable to various confidentiality threats because of its text nature and poor authentication mechanism. In this paper we have attempted to provide confidentiality to SIP signalling message by designing secured symmetric encryption algorithms. Algorithm performance is evaluated base on security strength, space and CPU utilization.
