> 中文摘要: 通过对传统CORBA(common object request broker architecture)体系结构的扩展,OMG(Object Management Group)提出的CORBA音/视频流服务规范使得多媒体应用可以获得分布式对象计算在开放性、标准化等方面的优势.但该规范在安全方面有所欠缺,没有提供解决分布多媒体应用所面临的安全问题的完整方案.通过引入CORBA安全服务,并定义数据安全服务的概念,对原有流服务体系结构进行了安全扩展,提出了一个完善的安全流服务模型SecStream,对其进行设计和实现,并加以实践应用,验证了该模型可以灵活地提供多种安全保证,并具有较大的可扩展性.
Abstract:The Audio/Video Stream Specification was brought forward by OMG (Object Management Group) based on the extension to traditional CORBA (common object request broker architecture) architecture. Multimedia applications could get more benefits, such as open and standard, from the distributed object computing brought by this Specification. However, there is not a whole scheme in the specification to solve the security problem of distributed multimedia applications. Because of this immature security, a security stream model―SecStream is presented, which brings the CORBA security service and the data security service into the old stream architecture. Subsequently, design and implementation of the above model are discussed. Finally, the SecStream model is successfully applied to an application, where the flexibility and extensibility of this model are verified.
