摘要
20世纪90年代开始计算机网络技术开始应用于安全管理,多年来技术手段虽然有长足的进步,但计算机网络应用水平还比较低,分布式应用系统处于起步阶段。该文介绍了分布式应用系统中信息安全的保障措施。结合混沌理论中混沌映射对初始条件的敏感性、具有白噪声的统计特性和混沌系列容易生成的特点,提出了一种采用混沌对称加密算法和一次性混沌口令身份认证技术用于增强系统安全机制的新方案。
Since 90th decade of 20th century, the technology of computer network has been applied in the safety management. Although there is substantial advance of technique means in the last years, the application level of computer network is still low. Distributed application system is still in the start stage. In this paper, the author introduces the means for ensuring the information security in the distributed application system. A new chaos - based scheme for enchancing distributed application system security is proposed. The basic idea is to utilize the chaotic map＇s characteristics of being sensitive to initial conditions, having the statistic property of white noises and being easy to generate chaotic sequences. The chaotic symmetric encryption algorithm and one - time chaotic password identity authentication method are given which can take over the existing security scheme.
