Abstract

Data Encryption Standard (DES) has been broken [1]. The classical alternative, triple-DES, is too expensive for many users, taking three times the computation of DES itself [1]. Therefore, the modified-I/O DES has been presented. The modified-I/O DES is based on DES but it is stronger than DES itself. It uses 120 bits key length and it is much faster than triple-DES.
