Combination of sustainable resources and expanded developments in vitality utilization have made new challenges for the traditional grid system. To confront these challenges, the Internet of Things (IoT) have changed the traditional grid system into a modernized electrical system which is called smart grid. In smart grid networking, security and privacy are the major concerns. Recently, various authentication and key agreement protocols have been presented in smart grid network with different privacy and security features. Although, some scheme suffer from different security and privacy challenges, some of them required much high computation and communication costs. To solve these challenges, we propose a lightweight authentication and key agreement protocol for smart grid which is free from key escrow issues and provides more security and privacy features. We provide a formal security analysis of the proposed scheme which is based on the random oracle model that indicates correctness of the proposed protocol. Further, we provide security verification of the proposed protocol by using AVISPA software tool. Also, we demonstrates the informal security of the proposed scheme. At last, we show the better efficiency of the proposed protocol in terms of communication and computation cost compare to others protocols in smart grid network.
