Abstract: The development of power networks is a trend of the future. These networks allow the two-way flow of power resources between users and power systems. As the key node for connecting users and energy systems, smart meters contain a large volume of user's power transaction data and identity information, which leaves the potential for a breach of private user data. To protect the privacy of the user, an identity authentication scheme for smart meters, based on blockchain technology, is proposed. The smart meter's identity information is processed using the Merkle-tree principle and stored in the blockchain; with this, the authentication of the smart meter's identity is realized and the identity information cannot be modified. Additionally, it breaks the connection between the user's identity and their power data, preventing internal and external hackers from obtaining private user data. The integrity and validity of the transaction data are guaranteed by using the characteristics of blockchain technology.
