Abstract
Smart grid is the next-generation grid that combines advanced power technology and modern communication technology. Smart meters face serious security challenges such as the leakage of user privacy and the absence of trusted third parties. Blockchain provides a viable solution that can use its key technologies to solve these problems. In blockchain technology, there is no necessary need of the third party in the energy supply sector. We introduce decentralization into smart grid, and a blockchain-based data aggregation scheme is designed. Due to the transparency of data in blockchain, the privacy of users may be disclosed. Therefore, our scheme adopts Paillier cryptosystem algorithm to encrypt the user’s electricity consumption data, realizing the confidentiality of electricity consumption data, which is convenient for billing and power regulation. Through performance analysis of the scheme, it shows that the scheme has better security and better functions.
