Implementation & Comparative Analysis of RSA, Caesar Cipher and Playfair Cipher

Abstract

With the growing use of the Internet, and more people being connected with it, the security of the data becomes a major concern. It is necessary that the data can only be accessed by the intended receiver and no person in the middle makes alterations to it. This is achieved by encryption of the data using cryptography. This paper presents a comparative analysis of RSA (Rivest-Shamir-Adleman), Caesar Cipher and Playfair Cipher cryptographic techniques. This paper also presents a comparative analysis of Symmetric Key Cryptography and Asymmetric Key Cryptography. Also, this paper includes the basic working of the above-mentioned techniques along with their implementation in C language over Visual Studio Code 1.49.3.
