Secure MODIFIED AES Algorithm for Static and Mobile Networks

Abstract

Security has been a primary concern for eachtype of network to provide secure communication among the users of different types of network. Presently, many techniques are present for providing security in networks but Advanced Encryption Standard (AES) has been proved to be the most prominent, keeping the data security as the major factor in data transmission. In the presented exposition, a modified variant of AES algorithm named as Modified Advanced Encryption Standard (MAES) has been introduced for secure data transmission in wired and various wireless networks namely, MANET, VANET, and FANET. The proposed technique focuses on both prevention and detection of the security attacks on the network. Theoretically, it is difficult to break the security or crack the key in the assumed network. The proposed protocol takes 2256 computations as compared to the basic AES standard which take 232 in case of differential fault analysis. The simulation results show that the proposed MAES outperformed AES in terms of security against attacks such as side channel attacks.
