ABSTRACT

DES is a kind of block cipher and before DES encryption the plain text be divided into the same-size blocks. But sometimes the plain text can’t be divided into the exactly size. So padding step is needed to pad the space of the block. The discussion of the block padding is the emphasis of this paper. A new padding method is given and at the last part of the paper the implementation of DES using new padding method is given.
