| Abstract |
: |
Data encryption standard in spite of being a great algorithm in terms of a good combination of confusion and diffusion steps, doesn’t largely used because of a weak key concept. The key used in DES is only 64 bits (or 56 bits) long. This paper introduces a concept of pre distributed powerful key for DES. In this for every round of DES a new key is getting used which makes cryptanalyst to attack not 56 bits but 16 keys of 56 bits each which makes it a much stronger algorithm. |
