A Study on Encyrption Algorithm using Number theory in Cryptography

Abstract

“A Study on Encryption Algorithm using Number Theory in Cryptography” deals with data security using Number Theory in Cryptography. Data is a key factor in the field of Information Technology where Encryption can be an excellent choice for keeping the data safe from potential data theft. ”Cryptography” is the method of secured information transfer by which no third party can access nor understand the message that sent. A mathematical procedure for performing encryption on data, is carried out by the use of an algorithm, where information is made into meaningless cipher text which requires the use of a key to transform the data back into its original form. The idea of encryption using Caesar Cipher and RSA public key cryptography is discussed in this paper. Mathematical concepts with prime, divisors, congruence and Euler’s function are employed in cryptography for guarding data.
