METHOD, DEVICE, AND SYSTEM FOR VERIFYING POINTS DETERMINED ON AN ELLIPTIC CURVE

摘要

Conventional cryptographic methods that are based on elliptic curves are prone to side-channel attacks. Previously known methods for preventing side-channel attacks have the disadvantage of requiring high arithmetic capacity and a large amount of available memory space. The inventive method overcomes said disadvantage by using a process for verifying points on elliptic curves which saves arithmetic capacity and memory space.
