摘要
电力信息系统为电力的生产、输送、变电和分配提供了极大的帮助,是电力自动化系统的重要组成部分。电力信息系统的安全涉及到人民的切身利益和国家安全,其安全性必须得到保证。信息系统的等级保护为电力信息系统的安全提供了有力的保障,分析电力信息系统中身份鉴别技术的现状和特点,针对电力信息系统的特点,提出一种基于SM2算法的身份鉴别方法。SM2算法相对于RSA算法具有运算速度快、安全性高等优点,目前已经成为国家密码管理局推荐的算法。首先介绍基于SM2算法实现身份鉴别的原理,阐述了在电力信息系统中基于SM2算法的身份鉴别系统的实现,最后给出了基于SM2算法的身份鉴别技术的结论。基于SM2算法的身份鉴别系统能够很好地解决电力系统身份认证的问题,并为系统用户行为的审计提供支持,具有很强的应用性。
As one of the most important parts of the power automation system, power information system contributes greatly to the power generation, transmission, substation and distribution. Since the security of power information system relates to the vital interests and national security of the country and people, its safety must be guaranteed. Classified protection of information system security provides a strong guarantee for the safety of the power information system. We analyse present situation and features of authentication technique in power information system, in light of the feature of power information system, we propose an SM2 algorithm-based authentication method. SM2 algorithm has the advantages of fast operation speed and high security in contrast to RSA algorithm, and has been the algorithm recommended by the State Cryptography Administration. In the paper we first introduce the principle of authentication implementation based on SM2 algorithm, then expatiate on the implementation of the SM2 algorithm-based authentication system in power information system, and at last we provide the conclusion of the SM2 algorithm-based authentication technique. This authentication system can well solve the authentication issue in power information system, and is able to provide support for auditing the system users＇ behaviours, it has very strong applicability.
