Privacy-preserving signed distance protocol
摘要
Abstract
Privacy-preserving signed distance is a special ease of secure multi-party computation problem and it can be applied in many fields such as military and commercial fields.Calculating the sign of the signed distance decision space geometric ob-ject's position is an essential method of processing spatial geometric object position.In this paper,one privacy-preserving signed distance protocol is presented to solve the signed distance problem based on scalar product protocol.The security and correctness of the protocol are also discussed.And then the privacy-preserving of the triangle intersection with the plane determines is taken as the example to explain its application.关键词
