【摘要】 文章分析了数据分发服务(DDS)通信中间件的基本架构以及DDS应用在舰载系统上的技术优势。针对DDS的信息安全研究现状提出了基于DDS通信的信息安全问题,根据信息系统的特点、安全域和DDS域的相似性提出了DDS安全域划分原则,根据信息安全策略和QoS策略对通信控制的功能相似性提出了"信息安全属性-信息安全策略yuanchao_whut@163.com策略"三级映射关系的QoS策略配置方法,最后通过实例分析说明了文章提出的方法针对指导实际系统划域和配置QoS策略的可行性。更多还原

【Abstract】 This paper analyzes the fundamental architecture of DDS Communicaiton Middleware and the technological traits of DDS’s application in shipboard system.For the current research on information security of DDS,this paper proposes the information security of DDS communication for the first time.According to the feature of information system and the similarity between security domain and DDS domain,it develops the division strategy of DDS security domain.On the base of similar control of communication between information security strategy and QoS strategy,it puts forward the QoS stragety configuration of information attribute-information strategy-QoS strategy.Finally,this paper illustrates the feasibility of the method using an living example.更多还原
