It is vital to the success of next generation of power grid, which is expected to be featuring reliable,efficient, flexible, clean, friendly and secure characteristics. In this talk,we dicussan efficient and privacy-preserving aggregation technique, named EPPA,for smart grid communications. EPPA uses a super-increasing sequence to structure multi-dimensional data and encrypt the structured data by the homomorphic Paillier cryptosystem technique. For data communications from user to smartgrid operation center, data aggregation is performed directly on ciphertext atlocal gateways without decryption, and the aggregation result of the originaldata can be obtained at the operation center. Through extensive analysis, wedemonstrate that EPPA resists various security threats and preserve userprivacy, and has significantly less computation and communication overhead thanexisting competing approaches.
