基于PDST-EEF机制的智能电网网络安全框架研究

无线传感器网络(WSN)可以实现智能电网的实时监测和控制,但其能源使用具有一定的约束限制。同时,拒绝服务威胁(如Do S和重放攻击)对智能电网网络安全产生严重破坏。为了解决这些问题,提出了基于便携式和数据安全容忍度的节能框架(PDST-EEF)。PDST采用加密签名认证方法来检测不同的攻击,从而保证数据隐私。EEF适用于智能电网跟踪,其以各个阶段为模型,如识别波腹、组群开发和密钥分配等,在保持长期延迟的情况下以更高的效率技术运行,以较少的能源实现电网网络安全可靠的运行。实验结果表明,PDST-EEF能够在保持持续性能和可靠性的同时以较少的能源使用量运行,而且相较于传统机制,能源使用量降低5.06%。

Smart Grid Cyber Security： An Overview of Threats and Countermeasures

The smart grid is the next generation of power and distribution systems. The integration of advanced network, communications, and computing techniques allows for the enhancement of efficiency and reliability. The smart grid interconnects the flow of information via the power line, intelligent metering, renewable and distributed energy systems, and a monitoring and controlling infrastructure. For all the advantages that these components come with, they remain at risk to a spectrum of physical and digital attacks. This paper will focus on digital vulnerabilities within the smart grid and how they may be exploited to form full fledged attacks on the system. A number of countermeasures and solutions from the literature will also be reported, to give an overview of the options for dealing with such problems. This paper serves as a triggering point for future research into smart grid cyber security.
