The Rivest-Shamir-Adleman (RSA) encryption algorithm is an asymmetric encryption algorithm that is broadly used in several products and services. Asymmetric encryption need a key pair that is mathematically connected to encrypt and decrypt data.A private and public key are generated, with the public key being available to anyone and the ...

Public key cryptography is called as asymmetric key cryptography. It is an essential encryption and decryption pattern in online software. It uses two different keys termed as public key and private key.In symmetric key algorithms, only one key is used to implement encryption and decryption operations. But in public key ... Read More

Public key cryptography has become an essential means of providing confidentiality, especially through its need of key distribution, where users seeking private connection exchange encryption keys. It also features digital signatures which enable users to sign keys to check their identities.The approach of public key cryptography derivative from an attempt ... Read More

## What are the Miller-Rabin Algorithm for testing the primality of a given number?

Ginni

Updated on 16-Mar-2022 09:48:55

Miller Rabin is a fast approach to test primality of the large numbers. This algorithm is called a Rabin-miller primality test and this algorithm decides whether number is prime which is same to other tests including Fermat primality Test and Solovay- Strassen primality test.This test is based on equality or ...

A primality test is an algorithm to decide whether an input number is prime. Some primality tests are deterministic. They always correctly decide if a number is prime or composite.The fastest known deterministic primality test was invented in 2004. There are three computer scientists, such as Agrawal, Kayal, and Saxena, ... Read More

Euler's theorem is a generalization of Fermat's little theorem handling with powers of integers modulo positive integers. It increase in applications of elementary number theory, such as the theoretical supporting structure for the RSA cryptosystem.This theorem states that for every a and n that are relatively prime −\mathrm{a^{\phi \left ( ...

S-Box Substitution is a procedure that accepts the 48-bit input from the XOR operation containing the compressed key and expanded RPT and creates a 32-bit output utilizing the substitution technique.The substitution is implemented by the eight substitution boxes (also known as the S-boxes). Each 8-S-boxes has a 6-bit input and ... Read More

## What is Modular Arithmetic in Information Security?

Modular arithmetic is a structure of arithmetic for integers, where numbers "wrap around" upon reaching a specific value. Modular arithmetic enables us to simply make groups, rings and fields which are the basic constructing piece of most modern public-key cryptosystems.For instance, Diffie-Hellman need the multiplicative group of integers modulo a ...
