Ahmed Elshafee . A 64 bits Dynamically Key Controlled Symmetric Cipher (KAMFEE-X64). International Journal of Computer Applications. 57, 13 ( November 2012), 16-24. DOI=10.5120/9174-3575
Abstract
This paper presents an improved version of KAMFEE cipher [1]. The proposed cipher (KAMFEE-X64) is designed to be compatible with the new 64 bits microprocessors unlike the old cipher (KAMFEE) which is designed for systems based on x86 microprocessors. KAMFEE-X64 has a key dependent block length and key dependent rounds, enhanced by a rotor. The number of rotor's wheels depends on key length too, rotor is implemented using successive 64 bits affine transformations. Its block is divided into basic blocks of 64 bits length. 264 modulo addition and 64 bits XORING are used. It uses 64 bits sboxes implemented using 64 bits affine transformation. Two steps of permutation are used, first step is basic block permutation and second step is basic block mixing. The strength of this system is compared with the KAMFEE and the well-known RC6, and RIJNDAEL ciphers. KAMFEE-X64 cipher gives excellent results from security characteristics and statistical point of view of. So authors suggests to use KAMFEE-X64 in the area of banking and electronic fund transfer.
