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).
