一种多级安全防护的过滤模型在智能配电网通信系统的应用

摘要

In order to realize the comprehensive and real -time monitoring, the widespread public Internet in the communica-tion system of smart grid occupies more and more proportion .In the public network of power system , the openness of smart distribution network gives the access of a large number of malicious attack entrances .In order to prevent the malicious terminal access to the communication system of smart distribution network , multilevel information security filtering model and integrated encryption technology are adopted so as to realize the security protection for information system of smart distribution network based on the hierarchical structure design of communication system in smart distribution network .The examples of integrated encryption communication programming show that the proposed scheme can improve the sensitive information security and prac -ticability .%为了实现全面和实时的监控，分布广泛的公用因特网将在智能电网通信系统中占有越来越多的比重。智能配电网的开放性为电力系统中公用网络接入了大量的恶意攻击入口。为了阻止恶意的终端接入到智能配电网通信系统，在智能配电网通信系统层次化结构设计的基础上，提出采用多级信息安全过滤模型和综合加密技术实现对智能配电网的信息系统的安全防护。综合加密通信编程实例表明，该方案增强电力网敏感信息安全性和实用性。
