Abstract
An encryption device for generating an electronic signature for security includes a random number generation module configured to generate at least one random number, a random number adjusting module configured to generate a one-time random number satisfying a random number condition in an elliptic curve cryptography-based digital signature algorithm (ECDSA) by adjusting the at least one random number; and an electronic signature generation module configured to generate the electronic signature using the one-time random number based on the ECDSA.
