| Abstract: | Digital signature of message recovery means that a verifier may verify correctness of signature and recover the signed message simultaneously; So the person who signs the message needn＇t send the signed message to the verifier when he sends a the signature. We propase a digital signature of message recovery based on self - certified cryptosystem, the scheme has the characteristic which the message may recover from the signature; the cost of computation and communication is low; in applications of E - commerce, it has more secure and more practical merits. |
