Non-Crypto Authentication for Smart Grid Based on Edge Computing

Abstract As a new computing architecture, edge computing has gradually penetrated into the smart grid and provide real time monitoring and control. However, as a new type of node arranged in the network, its own security protection has become an incredibly challenging task. Security authentication is the first line of defence for security protection. Due to its fast and light-weight characteristics, physical layer channel information access authentication technology for non-cryptographic packets is a potential identification method for the smart grid terminal access under the edge computing system, in which the real time response is incredibly important. This paper aims to investigate the physical layer authentication method compared with the traditional upper layer authentication technology, and an authentication scheme suitable for smart grid is proposed.
