基于混沌流密码体制的电子海图数据加密方法

电子海图系统作为导航信息的综合显示平台已被广泛应用于现代航海过程中.电子海图系统的信息安全直接影响船舶航行的安全,在研究军用矢量数字海图格式的基础上,给出其数据加密的方法,并且提出一种基于混沌流密码体制的保护电子海图系统信息安全的解决方案,阐明了电子海图系统数据保护方案的用户关系,明确给出数据保护方案的加密操作流程.该方案可以很好地支持电子海图数据服务于多用户的机制,适用于我国现行数据交换标准.

Electronic chart encryption method based on chaotic stream cipher

As an integrated display platform,Electronic Chart System(ECS) is now used in the process of modern navigation for ships.The information security of electronic chart system directly influences navigation security.The characteristics of the Military Vector Chart Format(MVCF),are also summarized.The encrypted way of MVCF data is also suggested.An integrated information security scheme based on chaotic stream cipher is proposed.A new method of encryption flowchart is introduced.The scheme is suitable for the multi-user who is served by the electric navigation chart,and could be the foundation of ECS security standard used for the current electronic chart exchange standard of China.
