Abstract:

The concept of smart grid has emerged as a convergence of traditional
power system engineering and information and communication technology. 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, I will present an efficient and
privacy-preserving aggregation scheme, 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
smart grid control center, data aggregation is performed directly on
ciphertext at local gateways without decryption, and the aggregation
result of the original data can be obtained at the control center. Through
extensive analysis, we demonstrate that EPPA resists various security
threats and preserves user privacy, and has significantly less computation
and communication overhead than existing competing approaches.
