Research Of E-commerce Security Based On Chaotic Encryption

E-commerce is an information system, which is the rapid development of Internet rapidly growing and popularity. In the system, its security is also decreased based on the development and popularization of Internet. In among measures of improving security e-commerce, the data encryption algorithm design and rational optimization is an important measure. This research is an encryption key for expansion space for the optimization of data encryption algorithm. Judging from the whole structure of this research, its methods used in the experimental simulation, examples corroborate data analysis. Its research major area is e-commerce security, studied mainly as data encryption, studied the main target is to encrypt key space. The main course of the study is as follows:First, the basic concept of information security, including information security definitions, trends and areas covered, so as to be a complete information system security down to the specific application areas, namely the field of e-commerce security. And then make this a field-level analysis, structured induction, which leads to e-commerce system security system in the central position.Then, according to the e-commerce security system at the core of e-commerce systems, e-commerce security system from a complete e-commerce system to separate out individual research. About the use of e-commerce, this summed up the thread of e-commerce security reasons, and then summed up a complete e-commerce security mechanism. And then the structural analysis of the security mechanisms that will eventually be refined to again research data encryption, which for this paper Chaos Theory Encryption Algorithm designs provides a premise.Third, from the chaos of the origin and development, definition, movement characteristics and judgment criteria and other aspects of chaos theory to make a brief introduction, and then based on the relevant characteristics of chaos theory leads to chaos and cryptography relationship between the design of Chaotic Encryption algorithm provides a theoretical basic. And from using chaotic Hash function construction ideas on chaotic encryption algorithm design to make a principle of analysis.Finally, the paper design chaotic encryption algorithm and has proposed a chaotic encryption key from the perspective of space to make a comparison, then the encryption algorithm is designed to achieve this purpose. In other word, iterative four chaotic Logistic maps can be extended so that the encryption key space.
