An Efficient Message Authentication for Non-repudiation of the Smart Metering Service

This paper proposes an efficient message authentication scheme providing non-repudiation of the smart metering service in Smart Grid. One of the main challenges in securing Advanced Meter Infrastructure is to accomplish message authentication and non-repudiation services in the metering service. Low power consumption of cryptographic operations in smart meter devices is another critical issue. The proposed scheme utilizes authentication values generated using linked two keys to reduce the number of signature operations. Our scheme provides the assurance of the integrity and origin of metering data. These features prevent either consumers or utilities from denying their authenticated metering data. Furthermore, the proposed scheme achieves low power consumption in the viewpoint of significant cryptographic operations.
