Because of the large volume and quick-change of real-time electricity data, users' data generally is stored in various cloud platforms, which are easily attacked by adversaries, and users' privacy is revealed by this disclosure of data indirectly. Therefore, in order to prevent the disclosure of privacy, it is necessary for cloud platforms to have an efficient, secure method to protect the real-time...
Truthful spectrum auctions have been extensively studied in recent years. Truthfulness makes bidders bid their true valuations, simplifying greatly the analysis of auctions. However, revealing one's true valuation causes severe privacy disclosure to the auctioneer and other bidders. To make things worse, previous work on secure spectrum auctions does not provide adequate security. In this paper, based...
Scalar product protocol and privacy preserving add to multiply protocol (PPAtMP) are two significant basic secure multiparty computation protocols. In this paper, we claim that the two protocols are equivalent to each other and we can achieve one based on the other with the same communication and computation complexity. Then, we propose Secure Two-party Mean Protocol, Secure Shared x ln x Protocol...
