In Depth Survey on SMS4 Architecture

In the present world, securing data is very necessary in every industry especially in defense sector and banking sector. Many encryption algorithms are proposed to prevent the data theft. In this paper various architectures of SMS4 algorithm is discussed. SMS4 is a Chinese standard cipher developed for securing information in Wireless Local Area Network (WLAN). This survey is done to propose a new modified SMS4 architecture, which can perform secure encryption and decryption better than the existing SMS4 architectures. Finally discussed about the possible ways of changes can be done for improvement.
