摘要
近年来安全模型的设计已经成为一个重要的研究课题。安全模型本质上是要满足给定系统的安全需求。文章以状态机模型为基础描述了一个简单抽象的网络安全策略模型SPM=<S,O,T,s0>,通过对系统在运行期间所要经历的不同阶段的安全状态讨论,给出了该模型的一个安全定理。
Recently,the designing of a security model has be-come an important problem.A security model essentially cap-tures the notion of security in a given system.this paper de-scribes a simple abstract network security policy model SPM=<S,O,T,s 0 >,based on a state machine.Through discussing the se-curity state in different phases gone through by the system dur-ing its operation,we get a security theorem of the model.
