Abstract


With the rapid development of network technology , IP video phones will be widely used . IP video phone to replace the traditional PSTN telephone has become the trend of the times , especially with the high-speed development of the information industry , the Internet-based IP technology-based next-generation network mode , IP video phone will lead the trend of modern communication . With the wide application of IP video phones , people are more and more emphasis on IP video phone communication security issues . This article comes from the National Eleventh Five topics , IP video phone security policy , an end-to-end IP video phone security policy design embedded security platform , platform security policy research group IP video phone developed jointly test to verify the correctness of the design of security strategies and security . The main work is as follows : start from the architecture and key technologies of IP video phone , the combination of the two aspects of the signaling control and media streaming IP video phone facing security threats , the existing IP video phone security policies according to their architecture level and compared , in-depth study of the existing security policy . Secondly , based on existing security policy , for the safety of the signaling protocol , designed for media streaming based on self-certified public key authentication key agreement protocol analysis of the safety and performance of the agreement ; safety , design the media stream SMS4 block cipher algorithm based security solutions ; combination of both as an end-to-end IP video phone strategy . Security policy analysis , pointed out the features of the policy . Finally, the use of dual-core DSP processor with dedicated cryptographic chip combination designed an embedded security platform for end-to-end IP video phone security policy . IP video phone with embedded security platform security policy , and with the research group has developed a joint tests to verify the correctness of the design of end-to-end IP video phone security policy and security .
