To overcome the disadvantages of designated-verifier signature schemes proposed by Dai and Wang, based on the Schnorr signature scheme, an improved designated-verifier signature scheme is proposed. The proposed scheme overcomes weakness of the schemes proposed by Dai and Wang. According to the security analysis, it is found that the new scheme is secure under the hardness assumption of discrete logarithm. On the other hand, the new scheme is more efficient than Wang's scheme due to its fewer exchanges than Wang's.
