基于Multi-agent理论的电力系统计算机网络的安全防护体系设计

Design of a Security System for Power System Computer Networks Using Multi-agent Theory

对基于Multiagent理论的电力系统计算机网络安全防护体系算法做了深入的研究,设计并实现了一种基于Multiagent理论的电力系统计算机网络的安全防护体系的分布式安全机制DSM的设计方案。该方案DSM结构分成低层和高层,低层提供加密的信道,采用混合使用RSA和Rabin加密的方法;高层实现权限的检查,采用访问许可表APL,由一个建立在电力系统计算机网络中的专门的认证中心ACAgent来完成各个Agent的登记、权限核实、修改草案等工作。通过理论分析和实践证明,该方案较好地满足了基于Multiagent的电力系统计算机网络中对安全性和实时性的要求。

This paper reviews the algorithms of security systems for power system computer networks using the multi-agent theory in depth and designs and implements the Distributed Security Mechanism (DSM) in a security system for power system computer networks based on the multi-agent theory. The DSM structure is composed of a bottom layer and a top layer. The bottom layer provides an encrypted channel using the mixture of RSA and Rabin encryptionmethods and the top layer examines the purview by using an Access Permission List (APL). In the top layer, a special Authentication Center(AC)agent is used to manage the registration, purview examination and draft modification of individual agent. According to the theoretical analysis and the practical experiments, the design satisfies both the security and real-time requirements of the security system for power system computer networks using the multi-mgent theory.
