Performance analysis of FPGA implementation of enhanced Two-fish encryption algorithm

In our latest data transmission and transportation, secured communications is most important task. The task can be achieved by incorporating proper encryption method which provides a fine solution. The encryption algorithm is the mathematical procedure performed on message. To cipher a message and to decipher it back to the original message is called encryption. The key is used for encryption process. Two-fish is one of the symmetric encryption algorithms and it is a strongest algorithm since it has large key stream and number of rounds. The encryption/decryption process is formatted using assortment security key levels to improve the performance of twofish algorithm significantly. The various set of keys is achieved by using fuzzy logic. The performance of enhanced two-fish algorithm is analyzed by using FPGA implementation.
