Security Issues for Smart Grid EC System

As a typical industry auto control system, security issue is a necessary task in order to guarantee safe and secure grid operation. The edge devices the local data processing and storage that provide a real time control, a low latency and also can play a role of the security gate, in which the terminal authentication, data privacy and data security can be provide. Due to the terminals of the SG are resource and computing constrained devices, the encryption security measurements are hard to perform on these devices. Physical-layer (PHY) security methods use the characteristics of the channel or the device fingerprints, which can run on the edge devices. Therefore, the terminals almost do nothing, which means these kinds of PHY security methods are light weight to the terminals. This paper introduced several PHY light weight authentication methods for the smart grid based on the edge computing and illustration their efficiency.
