A Sophisticated Secured Smart Metering System

Security has become very important for the smart metering system to maintain its user privacy and prevent its vulnerability which may cause information misuse and prevent it from sabotaging the system. Cyber-attacks, if not prevented, may cause instability in the energy supply which in turn negatively affects the infrastructure of the grid. Previous metering systems have many disadvantages such as the presence of transfer keys that have no encryption, the use of large numbers of keys in initial state, and the collection of consumption readings which depends on the number of smart meters in the chain. In this paper, an innovative authentication and security system designed for smart metering in smart grids is proposed. This new system is distinguished by its ability to protect the two ways of communication and its use of a small set of keys while not adding much complexity to the message size. Combining routing security to protect the gateways and access control list that monitors and filters traffic to enhance the overall security, the proposed model in this article proved to be efficient and secure.
