智能电网网络安全的发展与挑战

Development and Challenges of Cyber-Security for Smart Grids

智能电网是一个由分布式异构组件组成的系统,但却存在诸多的网络安全问题。对智能电网所面临的安全问题进行了概括总结,介绍了智能电网模型与系统框架,列举了一些常见的智能电网面临的网络攻击方式,并提出一些应对的策略,该策略是通过保护网络、保护设备、加密数据、检测攻击以及防御攻击来保障智能电网的保密性、完整性和可用性,指出组合安全策略是未来发展的主要方向。

Smart grid is a system composed of distributed isomerism modules,but there exist many network security problems.This paper carried out the summary for security threats faced by smart grid,introduced the smart grid model and system framework,enumerated some common cyber-attacks mode faced by smart grid and proposed some strategies and countermeasures against cyber attacks,which guarantees the security,integrity and usability of smart grid via protective network,protective equipment,enciphered data,detection attack and defense attack.It is pointed out that the combination security policy is the main direction of future development.
