Abstract

In this paper, a new approach is presented to develop the DES algorithm. Where DES is un-linear complex encryption system able to encrypt the information in high speed once applied onto entities that manipulate it. DES – Table is the new schema that uses two tables to encrypt the input as 64 bits and the out is 56 bits of cipher, and then use two inverse tables to decrypt the cipher to return the input from 56 bits of cipher to 64 bit of plaintext. By this schema we achieve emboldening results with maximum possible of confusion, non-obviousness and complexity of ciphering. [1]
