Abstract： Aiming at security problems in smart grid, This paper propose a secure billing scheme based on privacy protection to interact and calculate a large amount of privacy data and improve the privacy data protection. Additive homomorphic encryption and mixed multiplication homomorphic encryption ensure the security of real-time power data in communication, data aggregation, electricity expenditure calculation and billing verification. Meanwhile, 爐he aggregation signature technology has reduced the overhead of data authentication process. The security analysis and performance analysis of the proposed scheme show that the scheme has good security and high performance.
