摘　　要：近年来内部管理人员泄露网络数据库信息事件频出,现有的网络数据库已无法满足当今网络环境安全性的需求,人们亟需一种更安全的新型网络数据库。分析网络数据库安全威胁,设计一种基于CAS系统的网络数据库安全模型。在此基础上设计一种Logistic-Henon混沌加密算法,并从复杂度、密钥空间、初值敏感性三个方面对该算法进行仿真实验分析。该系统一方面提高了CAS系统中票据使用和数据传输的安全性,另一方面避免内部人员直接接触敏感数据和密钥,进而提高了网络数据库安全性。In recent years,there have been many incidents of internal managers leaking network database information.The existing network database has gradually failed to meet the security requirements of today s network environment.A new type of network database with higher security is required by all kinds of users.This paper analyses the security threat of network database and designs a security model of network database based on CAS system.On this basis,a Logistic-Henon chaotic encryption algorithm was designed,and the simulation analysis was made from three aspects:complexity,key space and initial value sensitivity.This system improves the security of tickets usage and data transmission in CAS system,and avoids the internal personnel from directly contacting sensitive data and key,thus improving the security of network database.
