开放系统环境中全局安全系统的设计与实现

Design and Implementation of Global Security System in Open System Environment

在开放系统环境中，由于节点分散，资源易于动用和管理者距远莫及等原因，系统极易受到各种非法操作和恶意攻击的影响．因此，安全性是系统的一个非常重要的问题．文中介绍了一种基于交易器的开放系统环境，分析了该环境中的安全需求和全局安全系统的结构；提出了适用于该环境中的全局安全系统的设计方案，并实现了该全局安全系统原型．

Security is very important in open system enviroment because of the systems are easily subject to illegal operations and intentional attacks. In this paper, the open system enviroment based on the trader is introduced, and security requirement and architecture of global security system in the open system enviromemt are analyzed. A design of a global security system used for the open system enviroment is proposed and its prototype implementation is given.
