RSA and ECC universal, constant time modular inversion
Szymon Sarna, Robert Czerwiński · AIP conference proceedings · 2021
Modular inversion is a crucial operation for performance and security of the public key cryptography. Unfortunately its use cases in the most popular algorithms like ECC and RSA are a bit different. It makes development of universal system/ algorithm for both of them difficult. This paper presents results of the constant time modular inversion algorithm development process which achieves high level of security in context of Timing Attacks and Simple Power Analysis which are basic but serious danger for cryptographic implementations.
