An Improved Pig Latin Algorithm for Lightweight Cryptography

Abstract

The security of data transmitted has paramount significance in the exchange and storage of information. Cryptography provides a solution to a lot of real-world data security problems over digital communication channels. While cryptographic algorithms are not the only requirement for providing security, but these are the first step toward providing the required security over data transmission and communication. Cryptography is the science of keeping messages secure from unauthorized recipients. In this paper, we present a new cryptographic algorithm which is an amalgamated version of Pig Latin, a popular argot or jargon and RSA, one of the most popular asymmetric key cryptosystems. The modified Pig Latin involves a layer of encryption using the cryptographic algorithm RSA to provide better security than RSA alone, thereby increasing the security. The practical performance of the algorithm is analyzed in terms of its empirical computational complexity. There are several cryptographic algorithms which are used to secure information in the form of encryption and decryption. The running time of the proposed algorithm is compared with a present cryptographic algorithm AES-128. Because of the simplicity of the algorithm, it can be implemented for messaging applications used in mobile phones and to secure data stored on other small storage devices.
