An Improved in Feistel Cipher Structure of Encryption

Rajesh Kumar

Abstract: In this paper, I propose an improved encryption algorithm that have the different Feistel cipher structure of encryption. So far, conventional Feistel cipher algorithms have difference structure of encryption. I devise my algorithm by inserting XOR operation in left half portion and inserting a function in right half portion of plain text. the proposed algorithm improves encryption security by inserting XOR operation in left half portion and inserting a function in right half portion of plain text. The proposed algorithm will be useful to the applications which require the same procedure of encryption.

Keywords: Feistel cipher, improved Feistel encryption
