摘要
保密路径判定是一种特殊的保密隐私的几何计算问题.基于保密点积协议和百万富翁协议提出了一种半诚实模型下的曲线与椭圆区域的保密相交判定协议,并对协议的性能进行了分析.该判定协议可用于解决保密路径判定问题.
Judging private path is a kind of special privacy-preserving geometric calculation.A new private-preserving protocol for judging the intersection of a curve with an elliptic is proposed based on the Private-Preserving Dot Product Protocol and Millionaires' Protocol under the semi-honest model along with analysis of protocol' capability.It can be used to solve the problem about judging private path.
