Method for Secure Delegation of Calculation of a Bilinear Application
Abstract:
A technique for secure delegation of calculation of a value f(X,Y) of a bilinear application in a computational server. The technique comprises: selection of two secret parameters a and b; calculation of the numbers Xa and Yb; supply of the two numbers Xa and Yb to the computational server; calculation of f(Xa,Yb) by said server; receipt of the value of f(Xa,Yb) from the server; extraction of the abth root of f(Xa,Yb).
Abstract(Chinese):

一种用于在计算服务器中安全地委派计算双线性应用的值f（X，Y）的技术。 该技术包括：选择两个秘密参数a和b; 数字X＆lt; a＆gt;和＆lt; b＆gt;的计算; 向计算服务器提供两个数字X a和/或SUP> b ; 由所述服务器计算f（X a ，Y ）; 从服务器接收f（X a ，Y ）的值; 提取f（X ， B）的ab 根。
