基于CORBA的安全系统设计与实现

CORBA（公共对象请求代理体系结构）作为一种面向对象的分布式计算技术被广泛应用于诸多领域，它能够解决应用系统所面临的异构问题，但同时也给系统带来了更多的安全威胁，而仅仅依靠CORBA安全服务不足以解决这些安全问题。文章即针对这一情况。设计并实现了一个完整的安全系统，该安全系统基于CORBA底层架构，为上层应用提供多层次、多粒度、实用、高效的安全服务，并同时与其保持低耦合关系，从而不影响系统本身的灵活度。

Research and Implementation of a CORBA-based Security Systems

As an object oriented distributed computing technology, CORBA (The Common Object Request Broker Architecture) finds its wide use in many areas, which can solve the alien net problem of the systems, yet it bring more security issues. This paper concentrates on putting forward a complete security model used in distributed systems. This security system is constructed with CORBA services as its bottom frame, and supply application systems with security services of multilevel, multi-granularity, practicality, high efficiency and full aspect. At the same time, the security system keeps a low coupling with the application systems, thus enabling the systems' flexibility unaffected.
