摘要
针对半诚实模型提出了空间两平行直线间距离的保密计算协议。确保互不信任的参与方分别输入各自隐私信息合作计算,同时保持各自信息的隐私性,并且不能通过中间结果计算出其他参与方输入的隐私信息,最终准确得到两平行线间距离,并且在理论上证明了协议的正确性和安全性。
This paper proposed a privacy-preserving computational protocol on the minimum distance between two three-dimension parallel straight lines based on semi-honesty model.Every participant in semi-honesty model inputted his information and no one tend to leak the information to others.They could not get others' private information by the intermediate results except sharing the output.Finally,this protocol outputs the distance between two parallel straight lines correctly.It gave the correctness and security proof.
