Abstract: Computing Modular multiplicative inverse is an important step in many arithmetic algorithms used in Cryptography. For example, Montgomery modular multiplication [2] is required to find out ...

ABSTRACT: This paper considers a decomposition framework as a mechanism for information hiding for secure communication via open network channels. Two varieties of this framework are provided: one is ...

ABSTRACT: There are settings where encryption must be performed by a sender under a time constraint. This paper de-scribes an encryption/decryption algorithm based on modular arithmetic of complex ...

From basic algorithms like Sieve, Bitwise-sieve, Segmnted-sieve, Modular Arithmetic, Big Mod to Primality test, CRT etc. all other advance number theory algorithms.
