PMAKE: Privacy-aware multi-factor authenticated key establishment scheme for Advance Metering Infrastructure in smart grid

Abstract

Advanced Metering Infrastructure (AMI) ensures bidirectional communication for analysis and improvement of energy usage between service providers and customers. Establishing secure and efficient key exchange has become an important issue for the Internet-based smart grid environment. To ensure a secure, reliable and efficient operation in the smart grid environment, AMI should be protected from security attacks. On the other hand, since smart meters are installed in customer’s homes and businesses without hardware protection mechanisms that could be susceptible to physical attacks, where a dishonest customer may attempt to temper the metering data in order to make differences in billing. In this paper, an efficient privacy-aware multi-factor authenticated key establishment scheme (PMAKE) is proposed. One of the notable properties of the proposed scheme is that it can ensure physical security of the smart meters. From the performance analyses, we can claim that our scheme is secure and suitable for the resource limited smart meters.
