摘要 数据分发服务(DDS)是对象管理组织(OMG)提出的一种适用于分布式实时系统的数据分发规范,该规范为应用程序提供了良好的系统接口与服务质量(Qos)控制,在保证实时性的同时为系统带来了良好的扩展性与灵活性,但该规范缺少对信息安全方面的考虑。本文通过分析数据分发服务信息安全方面可能面临的威胁,设计了数据分发服务的安全组件,利用扩展DDS内置主题与证书认证的方式,实现了一种数据分发服务的身份认证方法。 Data Distribution Service(DDS) published by Object Management Group(OMG) is a specification on data distribution service suitable for distributed real-time systems. This specification brings useful system API and fine control to the quality of service(Qos). With the DDS, system not only satisfies the request of real-time system, but also has better expansibility. However the DDS specification take less information security into account. This paper introduces a security plugin by analyzing the information security threats which DDS may meet and implements an identity authentication method by expanding built-in topic and certificate authentication.
