Abstract
Provided is an elliptic curve exponentiation apparatus that can counter the DFA when an elliptic curve exponentiation technique is used. A computation result verification unitreceives, as a computation result, an exponentiation-result-point (X, Y) from an elliptic curve computation unitThe computation result verification unitcomputes X+a×X+b, and computes Y, and outputs the received exponentiation-result-point when judging that Y=X+a×X+b, and does not output the received exponentiation-result-point when not judging that Y=X+a×X+b.
