舰船通信系统安全保密需求研究

舰船通信系统安全保密是实现整个舰船信息平台安全的关键和重点,文中参照舰船通信系统的主要功能结构,运用信息系统安全需求分析方法,从舰内通信系统、舰外通信系统和控制管理系统3个方面,分析了舰船通信系统存在的安全保密威胁,提出了舰船通信系统安全保密需求框架,并在网间系统安全隔离、内网安全防护、安全接入、信息加密与数字签名,以及综合安全管理5个方面进行了深入的需求分析。

Study on Security ＆ Secrecy Demand of Ship Communication System

The security secrecy of ship communication system is the key and focus to the security of whole ship information platform.In reference to the function and structure of ship communication system and with the analytical method for the security demand of information platform,this paper analyzes the existent security threats of ship communication system from the three aspects as inside and outside the communication system and control management system,proposes the framework for security secrecy demand of the ship communication system,and then makes in-depth analysis on five aspects as network insulation,intranet security,secure access,information encryption,digital signature,and comprehensive security management.
