【摘要】 随着Internet的普及,电力企业网络安全问题日益突出,信息网络的安全将直接影响电网的稳定运行,PKI和PMI技术是电力企业中广泛应用和推广的认证和授权方式。本文以PKI/PMI为基础,根据电力行业多个信息系统的集成趋势设计了单一登录系统,并应用代理机制,该系统既能符合电力企业网络信息安全要求,又符合电力信息系统的发展方向,具有良好的兼容性和扩展性。在无人值守变电站中,普遍应用的是综合自动化系统,授权方式将影响自动化网络的安全,本文基于其结构特点,设计了分布式基于角色的访问控制方法,算法的设计符合ITU-T X.509和IEC61850国际标准,具有较高的实用性和适应性。更多还原

【Abstract】 For the popularization of Internet, electric power network security is more and more important. Security of electric power enterprise information network will directly infect running stability of electric power network. PKI and PMI are the widely used and extended authentication and authorization method. Based on PKI/PMI, a single sign-on system is designed to adapt to the integration trend of many information systems in electric power enterprise. Agent mechanism is used. It not only answers for the request of electric system, but also accords with the developing direction of the electric information system. It has a good compatibility and expansibility. Integrated automation substation system is widely used in unattended substations. The authorization mode will affect the security of the automation net. Considering its special configuration, distributed RBAC access control method is designed. The algorithm accords to the ITU-T X.509 and IEC61850 international standards, and has high currency, adaptability and expansibility.更多还原
