Abstract
One embodiment relates to a method for enabling an entity to delegate calculation of a bilinear pairing value e(A,B) between two values A and B to a calculation server. The entity may select public elements Pand Pand secret elements Sand S, two of the elements from among P, P, S, and Sbeing selected to be equal to A and B, generate elements R=vS, R=uS, T=uP+S, T=vP=S, whereandare random numbers, and transmit R, R, T, and Tto the calculation server. The server may calculate (a)=e(T,T)[e(R,P)e(P,R)], and (a)=e(D,D),anddesignating two integers equal to 1 or to an integer, Dand Ddesignating two public elements from among A and B or from among Rand Rand transmit aand ato the entity. The entity may obtain the value e(A,B) from aor a
