  7. Abstract:
  8. The development of distributed energy resources across the smart grid has led to a need for a secure and smart-grid-compatible auction scheme which can provide the grid users with the possibility of trading electricity. One of the most used types of auctions in the smart grid is the double auction, in which both buyers and sellers can respectively submit their bids and asks to participate in the auction. In recent years, many schemes have been designed to propose a double auction mechanism for the smart grids; however, few of these schemes consider the information security aspects and users’ privacy. In this thesis, we propose a protocol which helps different double auction mechanisms be implemented securely in the smart grids. This protocol not only can satisfy the security requirements of a double auction scheme but is also compatible with the smart grid technologies. In this scheme, in order to preserve the users’ anonymity and privacy, a pseudo-identification is assigned to each participant and the bids/asks are encrypted using the Paillier cryptosystem. By virtue of the Pedersen commitment scheme used in this paper, the participants can be verified as having correctly and honestly followed the auction protocol. Moreover, the proposed scheme is more efficient than the other existing secure double auction schemes in terms of both communication and computational overheads on participants’ side, making the auction process more compatible with smart grid users, who are characterized by low computing power and low bandwidth
