Secure Electronic Transactions And Application Of Cryptographic Algorithms

With the computer, communications and network technology development and popularization of cryptography has moved from diplomatic and military fields to open, has developed into a combination of mathematics,computer science, electronics and communications, microelectronics technologies such as cross-disciplinary. With the continuous development of INTERNET technology, people are increasingly adapting the concept of advances in information technology, e-commerce in such an environment has developed rapidly, however, e-commerce transactions, the two sides of the security and confidentiality is very important He is directly related to the future development of e-commerce. This thesis is divided into a total of four parts.Preface is the first chapter of the study briefly described, followed by the introduction of the domestic information security research status and the achievements made to strengthen the place to be for the SET, and finally that the starting point of this thesis and research value.ChapterⅡfirst encryption algorithm and then elaborate e-commerce transactions, followed by works on the agreement and protocol performance was briefly described and analyzed.ChapterⅢis the main part of this paper. This section mainly describes in Cryptography RSA algorithm is widely used in various parts of the process were analyzed, in the storage of large numbers put forward their views, and in some algorithm the time complexity of the process of certain aspects of the research.ChapterⅣwill present things in terms of security from different security levels have been studied, some of its security technology are described, as well as how to conduct in the future application of SET.This paper will now have a very sophisticated electronic analysis of secure transaction protocols, for which part of the performance put forward their own views, and the things in the future trading environment, the security of electronic security. Trying to e-commerce environment in the current INTERNET security and the situation of things in the future development of electronic commerce and application under intensive study.
