| Abstract: | Two improved discrete logarithm digital signature algorithm were analytical attacked. It was found out that, using the forgery attack, the receiver could fake the signer to generate valid signature. The cause of the attack was analyzed and new improved algorithms were presented. The efficiency of the new improved algorithm had increased significantly compared with existing signature algorithm. |

| Keywords: | discrete logarithm digital signature forgery attack improvement |
