| Abstract: | Special secure multi - party computation is one of the research focuses of the cryptography. As a special case of secure multi - party computation problems, privacy - preserving computational geometry has a broad application prospect. In this paper, finding secure two party convex hulls is studied. With STPCH protocol, PPCHP _ QH protocol is improved, and then a privacy - preserving protocol for quickly generating two party convex hulls is presented. It also discusses and analyzes the correctness, security and complexity of the protocol. The protocol is better than STPCH protocol and PPCHP_ QH protocol. |
