As Internet has been developing fast, network technology goes deep into almost every side of society and economy.The requirement for the security of the data transmitted, stored or processed will be more and more exigent and important. The aspects that information security has been researched are abroad, so the study of the encrpytion is one of the most important key technique.In this thesis, the author has studied on encryption sever. First introduce many encrpytion algorithms have been used in the sever, then, is the design theory of the encrpytion card .The author has studied the core of SSX04 and SSP02-A. I discussed the dependability of the encrpytion system and posed the concrete measures. THE MAIN WORK:The research object and the design theory;The component of the encryption server;The core of SSX04 and SSP02-A;The design of the encryption card. |
