Hybrid Security Algorithms for Data Transmission using AES-DES

Abstract

The fast evolution of digital data exchange has forced the information security to be of much important in data storage and transmission. As large amount of data is transmitted over the network, it is preliminary to secure all types of data before sending them. The problem with AES, most extensively used encryption is that it uses many multi variant equations which are linear in nature. Thus it can be broken using algebraic cryptanalysis. This provides a serious threat as AES was considered to be unbreakable and thus it was used in many encryption systems. The current paper presents the design and implementation of a hybrid based 128 bit key AES-DES algorithm as a security enhancement.
