Aiming at the problem of big data security and privacy protection in smart grid, the key technologies of big data security and privacy protection in the current smart grid are reviewed. In ac-cordance with the technology route for privacy-preserving big data analysis and mining in smart grid, a kind of privacy-preserving schemes for association rule mining is proposed. It adopts simple addi-tion secret sharing scheme to encrypt meter data and send them to the trusted third party. The sum of the meter data is achieved by secure aggregation protocol, and the support and confidence of associa-tion rule are computed by secure multiparty computation. The privacy-preserving big data mining makes the electric power company to improve the quality of service under the premise of not disclo-sing customer privacy information.
