Implementation of DES Encryption Arithmetic based on FPGA

It is very necessary for embedded applications to protect important data. A realization of the data Encryption Standard algorithm based on FPGA is presented in this paper. The implementations of the DES (data encryption standard) algorithm based on hardware is a low cost, flexible and efficient encryption solutions. This paper uses a method of iteration of the loop, with key size of 128 bits and realized by lookup table based on S-box. The simulation waveform showed that result in FPGA meet the requirements.
