Abstract: The smart grid (SG) is an efficient and reliable framework capable of controlling computers, automation, new technologies, and devices. Advanced metering infrastructure (AMI) is a crucial part of the SG, facilitating two-way communication between users and service providers (SPs). Computation, storage, and communication are extremely limited as the AMI’s device is typically deployed outdoors and connected to an open network. Therefore, an authentication and key agreement protocol is necessary to ensure the security and confidentiality of communications. Existing research still does not meet the anonymity, perfect forward secrecy, and resource-limited requirements of the SG environment. To address this issue, we advance a lightweight authentication and key agreement scheme based on elliptic curve cryptography (ECC). The security of the proposed protocol is rigorously proven under the random oracle model (ROM), and was verified by a ProVerif tool. Additionally, performance comparisons validate that the proposed protocol provides enhanced security features at the lowest computation and communication costs.
