Anup Kumar %J International Journal of Advanced Computer Sciences and Applications %D 2013 %I The Science and Information (SAI) Organization %X In this investigation, we have developed a novel block cipher by modifying classical Feistel cipher. In this, we have used a key bunched wherein each key has a multiplicative inverse. The cryptanalysis carried out in this investigation clearly shows that this cipher cannot be broken by any attack. %K encryption %K decryption %K cryptanalysis %K avalanche effect %K multiplicative inverse. %U http://thesai.org/Downloads/Volume3No12/Paper_14-A_Novel_Feistel_Cipher_Involving_a_Bunch_of_Keys_Supplemented_with_XOR_Operation.pdf
