But the cost can be reduced if different coordinate systems utilized. This paper shows that the performance of an elliptic curve digital signature algorithm (ECDSA) can be significantly increased by using different coordinate systems.eninfo:eu-repo/semantics/closedAccessAffine coordinate systemComputational costs of EC arithmeticECDSAElliptic Curve ArithmeticProjective coordinate systemConference Object2-s2.0-84893175522
