A New Secure Method for Determining Two Spatial Geometric Objects Related Position
Yi Lei · Computer Technology and Development · 2011
Mainly aims at two spatial geometric objects related position judging problem proposes a kind of new solution,using the concept of matrix Zhi and the secure protocol for the sum of two matrices to judge two spatial geometric objects related position problem.As for this problem,professor Luo Yonglong also designed a protocol for determining whether two sets of data are proportional correspondingly,but this text uses the concept of matrix Zhi and the secure protocol for the sum of two matrices to design some secure protocols for determining two spatial geometric objects related position.Using these protocols to judge the problem of the flat surface and the flat surface related position in the space,to judge the problem of the flat surface and straight line related position in the space and to judge the problem of straight line and straight line related position in the space.In this paper,a new judging method is developed,it solves two spatial geometric objects related position judging problem,will also have important function in the other secure multi—party computation problems.
