一种基于云计算的电力通信安全防御系统研究与设计

Design of power communication security defense system based on cloud computing

电力通信网是实现智能电网的基础,其可以实现信息共享和传输,承载的应用软件非常多,比如变电站系统、设备运维系统、电力监控系统、远程抄表系统等;部署的服务器也很多,比如传感器、交换机、路由器、服务器等。电力通信软硬件资源集成在一起时,由于开发技术、架构、功能均不相同,各个系统存在不兼容或仅部分兼容的问题,造成系统运行存在漏洞,面临着严重的安全威胁。因此,为了提高电力通信网络安全性,文中引入了云计算技术,构建了一个多层次的安全防御系统,并且给出了关键实现技术,进一步提高电力通信安全性能。

Power communication network is the basis to realize smart grid, it can realize information sharing and transmission, and carry many application software, such as substation system, equipment operation and maintenance system, power monitoring system, remote meter reading system and so on. Many servers are deployed, such as sensors, switches, touters, servers, etc. When the hardware and software resources of power communication are integrated together, because of the different development technology, architecture and function, each system is incompatible or only partially compatible, which makes the system running vulnerable and facing serious security threats. Therefore, in order to improve the security of electric power communication network, the cloud meter is introduced in the paper. In this paper, a muhi-level security defense system is constructed, and the key implementation techniques are presented to further improve the security performance of power communication.
