Comparison of Traditional and Elliptic Curves Digital Signatures Providing the Same Security Level

Abstract

The paper presents the efficiency comparison of different digital signature schemes taking into account both digital signatures based on algebraic groups of numbers and digital signatures based on elliptic curves. This efficiency comparison of two types of digital signatures is possible under the condition that for each scheme the appropriate key length was taken ensuring the same level of security. The paper show that the key length for classic digital signature needs to be greater than the key length for elliptic curve digital signature and thus different processing speed is observed.
