电力软交换系统及其安全性研究

电力行政和调度电路交换网向软交换系统演进是必然趋势。软交换是承载于IP分组网上的数据通信系统，可同时传输数据、语音和视频等信息。但同时软交换由于其开放、复杂等特点，无论在网络硬件开发、协议设计还是应用软件开发上，都面临着各种各样的安全威胁。在分析电力软交换系统安全威胁的基础上。从业务安全、信息安全、设备安全和网络安全等多方面提出安全方案，保证电网稳定运行。

Research on Electric Soft-Switch System and Security

The evolution from administrative switching and dispatching exchange to soft-switch system in electricity is an inevitable trend. The soft-switch system is the packet IP-based data communi- cations system essentially, which can transmit data, voice and video and other information. But at the same time, because of its open and complex feature, soft-switch faces with a variety of security threats in the development of network hardware, protocol design and application soft- ware development. Analyzes the security threats faced by electric soft-switch, puts forward se- curity schemes on business security, information security, equipment security and network secu- rity to ensure stable operation of power grid.
