発明の名称 (英語) PAIRING ARITHMETIC DEVICE, PAIRING ARITHMETIC METHOD AND RECORDING MEDIUM HAVING PAIRING ARITHMETIC PROGRAM RECORDED THEREON
発明の概要(英語) A pairing arithmetic device is provided with a CPU which calculates pairing e(S,Q), with F as a rational function calculated using Smember G1,Qmember G2, a predetermined integer variable as [GREEK KAPPA SYMBOL] , and an algorithm (MMA) of a mirror with respect to multi-pairing as F. The order r, the trace t of the Frobenius endomorphism map/image [GREEK PHI SYMBOL] p are specified using the integer variable [GREEK KAPPA SYMBOL] according to the degree of embedding k. The CPU carries out the arithmetic operation by means of: an inputting means which inputs the aforementioned integer variable [GREEK KAPPA SYMBOL] , the rational point S, and the rational point Q into their respective predetermined registers; a calculating means which calculates F; a calculating means which calculates values at a rational point Q(xQ,yQ) on a straight line which passes through predetermined rational points; a calculating means which calculates f' [GREEK KAPPA SYMBOL] ,s(Q) using F and the aforementioned value; and a calculating means which uses f' [GREEK KAPPA SYMBOL] ,s(Q) to calculate the pairing e(S,Q) as a [83].
