A Comp r ehensive Evaluation and I mplementation of AES, RSA and Hybrid Cryptographic Algorithms on a Portable Device

Abstract

In today’s internet era, at every moment terabyte of data being generated. It is a challenging task to provide security to such huge data. Cryptography is used as a tool in the modern world to safeguard this data from any attacks. There are many standard cryptographic algorithms available which can be used to protect data. These algorithms vary in cost and performance. Amongst the available standard cryptographic algorithms, we chose AES which is a symmetric encryption algorithm and RSA which is an asymmetric encryption algorithm and a hybrid combination of both for performance analysis. This paper makes elaborate discussions on performance analysis of AES, RSA and AES-RSA Hybrid algorithms and their implementation on a portable device for flexibility and portability.
