Conventional DES has been not only shown to have a vulnerable drawback to attack method called ‘Meet in the Middle’, but also to be hard to use that it is because software implementation has a number of problem in real time processing. This paper describes the design and implementation of the expanded DES algorithm using VHDL for resolving the above problems. The main reason for hardware design of an encryption algorithm is to ensure a security against cryptographic attack because there is no physical protection for the algorithm written in software. Total key length of 352 bits is used for the proposed DES. The result of simulation shows that the inputted plaintext in cryptosystem are equal to the outputted that in decryptosystem.
Abstract
Conventional DES has been not only shown to have a vulnerable drawback to attack method called ‘Meet in the Middle’, but also to be hard to use that it is because software implementation has a number of problem in real time processing.

The main reason for hardware design of an encryption algorithm is to ensure a security against cryptographic attack because there is no physical protection for the algorithm written in software. Total key length of 352 bits is used for the proposed DES. The result of simulation shows that the inputted plaintext in cryptosystem are equal to the outputted that in decryptosystem.
