摘要
随着智能电网建设的不断推进,电力系统的自动化水平逐渐提高。作为智能电网的重要组成部分,配网自动化的信息安全是智能电网发展急需解决的关键问题。为了防止不合法的终端设备接入到配网通信系统,根据现有配网通信系统模型的特点,以密码技术为基础,采用PKI密码协议,提出一种基于身份认证的配网访问控制方案。经过分析表明,该方案可以有效控制配网通信系统中设备的接入问题,对于提高配网自动化通信系统的信息安全具有重大意义。
With the continuous progress of the smart grid construction,the automation level of power system gradually increased.As an important part of smart grid,information security in distribution automation is a key issue that is needed to be resolved in the development of smart grid.In order to prevent illegal electronic communication devices from accessing to the communication system,according to the features of existing distribution network communication system model,an identity authentication access control solution is proposed based on cryptography.The analysis shows that it can effectively control the device access in communication system,and it has great significance to improve the information security of communication systems in distribution automation.
