A Note on the Computation of the Modular Inverse for Cryptography
Michele Bufalo, Daniele Bufalo, Giuseppe Orlando · Axioms · 2021
In literature, there are a number of cryptographic algorithms (RSA, ElGamal, NTRU, etc.) that require multiple computations of modulo multiplicative inverses. In this paper, we describe the modulo operation and we recollect the main approaches to computing the modulus. Then, given a and n positive integers, we present the sequence (zj)j≥0, where zj=zj−1+aβj−n, a
