安全判定两组数据对应成比例的新方法

A new secure method for determing two sets of data proportional correspondly

针对秘密判定两组数据对应成比例问题提出一种新的解决方案,即运用同态加密方案设计一个安全求解两组数据中对应成比例个数协议,并利用此协议进一步设计出安全判定两组数据对应成比例协议和安全判定空间中两平面的位置协议。该方法不但解决了安全判定两组数据对应成比例问题,还解决了空间两平面的相对位置判定问题。与以前的解决方案相比,设计方案不但提高了协议的效率,还降低了通信量。

Aiming at a secret to judge two sets of data proportional correspondly problem, this paper puts forward a new solution, which uses homomorphic encryption to design a safety protocol for computing piece of two sets of datas proportional correspondly. And by using this protocol, it designs a safety protocol for determining two sets of datas proportional correspondly and a safety protocol for determining two spatial flat surface related position. This method not only solves a secret to judge two sets of datas proportional correspondly problem but also solves two spatial fiat surface related position determining problem. Compared with other solutions, this method not only raises the efficiency of the protocol but also lowers correspondence.
