with an HMAC. HMAC is formed in this way: first, a data structure is established, which includes Alice's temporary value, Bob's temporary value, their identification, and shared secret key KAB; then hash the data structure and the hash result is HMAC. When Alice received message 2, she now had the identity of Ra, Rb, both sides, and secret key KAB, so she could also calculate HMAC. if the calculated HMAC is the same as the HMAC in the message, she knows that she is talking to Bob. Alice also

Network integration of video surveillance services based on Ngn/ims (SIP Protocol) communication Platform

I. Overview Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveillance, remote access, centralized management needs. The industry has explored two ways to solve the problem: From the monitoring industr
