摘要
CORBA为解决异构环境的应用提供了很好的基础,其安全性一直是备受关注的重点。CORBA通知服务弥补了事件服务中存在的两个重要缺陷,增加消息过滤机制和服务质量控制。OMG提出CORBA拦截规范[1],使得CORBA系统的对象调用更加安全可靠。本文深入对CORBA通知服务和CORBA拦截机制进行研究,把事件通道同拦截机制结合,设计出一种更安全可靠的通信机制。
CORBA provides good functions for the use of distributed environment,and its＇ security is taken more attentions all the time. Notification Service of CORBA is the complement for the two important limitation of the Event Service,adds filter-mechanism and QoS. OMG brings forward CORBA interceptor specification to make the Objects＇ transfer much safer and more reliable. This paper studies the Notification Service and interceptors-mechanism of CORBA,combines the Event channel with interceptors-mechanism,schemes out the much safer and more reliable communication-mechanism.
