基于一般系统论的信息安全系统的理论研究

Theoretical Research about Information Security System Based on General System Theory

基于一般系统论,从一个全新的角度来研究信息安全系统,为信息安全系统的理论研究开辟一条新道路,先用层次分析法分析信息安全系统的影响因素以及它们之间的相互关系,再通过微分方程模型来研究其中一些因素的相互作用。结果表明,该模型能从一定程度上展现出信息安全系统发展中的内部变化,对信息安全系统的发展起到一定的引导作用。

Nowadays, researches on information security mainly focus on practical technologies, and many of them, such as quantum cryptography, intrusion detection, and disaster recovery, have been highly developed and widely used. However, from the theoretical perspective, there is still a lack of systematical theory which can dominate the operation and guide the development of the information security system from a certain level. In this paper, information security system is researched from a new perspective based on general system theory for the purpose of providing a new way to study information security system. Analytic hierarchy process is adopted to analyze the influencing factors of information security system and relationships among the factors themselves. Then, the interaction among some of the factors is studied through a model of differential equations. As the results show, the model in this paper reflects the inner changes of information security system to a certain extent, and plays a guiding role in the development of information security system.
