【摘要】：随着社会的发展,智能电网应运而生,智能电网的出现极大地方便了人们的生产和生活,但是与此同时越来越多的隐患也威胁着智能电网的信息安全。因此智能电网信息安全性问题是目前智能电网研究迫切需要解决的问题。智能电网的发展迫切的需要与之相适应的信息安全技术来保证系统的安全运行。智能电网的信息安全主要包括物理安全、网络安全、数据安全及备份恢复等,除此之外智能电网还会面对由多网融合引发的新的安全问题。本文首先对智能电网的体系结构进行了介绍和研究,进而分析了智能电网信息系统存在的安全隐患。本文从智能电网的实际特点和实际中遇到的安全隐患出发,设计了一种接入控制方案,方便了密钥的管理与维护,这样系统生成的私钥可以被安全的保护下来,所有网外设备试图接入到电网内部前都要完成注册,否则不会获得访问系统内部的权限。在此基础上提出了一种基于Hash函数的数据完整性认证方案,在判断数据在传输过程中有没有被篡改的同时,也对是否伪造消息做出了判断,很好的解决了目前智能电网信息安全存在的问题。
[Abstract]:With the development of society, smart grid emerges as the times require, the emergence of smart grid greatly facilitates the production and life of people, but at the same time, more and more hidden dangers also threaten the information security of smart grid. Therefore, the security of smart grid information is an urgent problem to be solved in the research of smart grid. The development of smart grid urgently needs information security technology to ensure the safe operation of the system. The information security of smart grid mainly includes physical security, network security, data security and backup and recovery. In addition, smart grid will face new security problems caused by multi-network convergence. In this paper, the architecture of smart grid is introduced and studied firstly, and then the hidden danger of security in smart grid information system is analyzed. Based on the actual characteristics of the smart grid and the hidden security problems encountered in the practice, this paper designs an access control scheme, which facilitates the management and maintenance of the key, so that the private key generated by the system can be protected safely. All off-network devices must be registered before attempting to access the power grid, otherwise they will not gain access to the system. On this basis, a data integrity authentication scheme based on Hash function is proposed, which determines whether the data has been tampered with or not, and whether the data is forged or not. A good solution to the current smart grid information security problems.
