Compact and High Speed Hardware Implementation of CLEFIA

Abstract: Since 19^th century, we were get aware of the process of communication. But, from the last 3 or 4 decades we knew how the communication is essential for entire living. It is just a process of conveying information from one end to another. One end is known as transmitter and other a receiver.  For the success of communication, there should be presence of these both. As the use of this process goes on increasing, different methods or strategies were established. Afterwards the human being experienced that, not only the communication is important but also its safety is important. To achieve safety of communication many methods are used. But, the best method while using communication is Cryptography. Clefia is one algorithm used in Cryptography. It is 128 bit block cipher algorithm. This paper presents the different work done on Clefia by different authors. Also it proposes a method for the implementation of Compact and High Speed Hardware of CLEFIA.
