| With the rapid development and popularization of the Internet, Internet applications in business and society are increasingly being used up, and as the basic Internet protocols, TCP/IP protocol to its simple-to-use design principles for the development of the Internet made an important contribution, but it also brings more security risks. In the TCP/IP protocol design at the beginning, the network does not exist malicious users and did not give much thought to the safety factor. It just makes a lot of forged source address attacks take advantage of, such as Dos, DDos attacks and other social and personal information security posed a great threat.The researchers also asked for the related put forward some solutions, such as IPsec, SPM, Passport, etc., has a variety of advantages and disadvantages of each option and scope, the proposed scheme has absorbed SPM SMA and some other programs advantage by building trust alliance, in the Ministry of autonomous region by generating packets add tags to verify the way the label is based on the dynamic label state machine, which would also improve the reliability of inter-domain communication.This paper first analyzes the SMA mechanism ACS-related needs to communicate with other devices, and then made to communicate with the AER in ACS registration information, deploy query response message packet label design, prefixes and keep-alive packet of information, and corresponding record field of design, and the design of the packets based on the above needs, IOC’s platform ACS end coding work-related functions, from the communication mechanism, the command-line user interface design, and data storage areas to achieve a smooth inquiry carried out display, best describes the final project related test methods and test results. |
