Digital signature is a key technology and has a comprehensive application in secure e-commercial exchange.A new and efficient signature scheme is proposed,and its security is reduced to computational Diffie-Hellman problem without using forking reduction tech-nology.Furthermore,a comparison and analysis between the proposed signature scheme and other signature scheme without using forking reduction technology is given on computation cost and communication overhead.The result shows that the proposed signature scheme has the advantages of shorter signature and less bandwidth.
