The Research Of Entropy Analysis Method For Information System Security

With the deepening of information technology, computer information system security is also facing new challenges. There are shortages among the existing model of information security, security technology, security analysis technology and security evaluation technology. Therefore, it is of great significance to research and analysis of information system security entropy method.Based on the theories of entropy, this paper analyses the basic relationship between information systems security and entropy and researches entropy analysis method for information system security. The following is the paper's main works and efforts.First, this paper analyses the basic relationship between information system security and entropy. This paper researches the relationship between information system security and entropy change by analyzing the information system's dissipative structures based on the theories of entropy.Second, it proposes the concept of information system security entropy. This paper gives the definition of information system security entropy and its mathematical description from the point of security attributes, and analyses its meaning and significance.Third, it analysis the features and drawbacks of the traditional security approach, proposes the information security framework for the process of entropy analysis and proves some conclusions.Forth, it researches the key points of the application of entropy analysis. It discusses on how to use the method from the scope of application, a typical process and concrete implementation of the process.Fifth, it researches the approach of information system security in the archives protection system. The approach is used to analysis the security of the system architecture. The correctness of the theory is proved by a number of tests.All these researches aim at the goal of analysis the security of information system. Entropy and information system security are combined and the theory of entropy analysis is researched in-depth and combined with the application. Research shows that the method has a certain value of theory and application.
