Abstract: In this paper the communication processes of ordinary digital signature is discussed. The defect of the ordinary digital signature is that ,the receiver may deny received communication message and no anyway to restrict it. Therefor based on the cryptosystem which combines conventional ,cryptosystem with public-key and adds a key-word set a better method of digital signature that receiver can not deny is proposed in this paper.
