摘　　要：在ElGamal公钥体制上提出了一种盲签名方案,较之基于RSA算法的盲签名方案有其明显的优点。通过有向因子的引入,在真正意义上实现了电子交易中的匿名特性。通过对其安全性的分析,证明了该算法达到了安全性和可操作性的实际要求,必将有利于推动电子商务的发展。This paper presents an efficient blind signature scheme based on the ElGamal signature, which has distinct advantages over original blind signature schemes based on RSA algorithm. By introducing directed algorithms, the characteristic of anonymity in the electronic transactions of business has been really completed. By analyzing the performance security, the algorithm can meet the requirements of performance security and the capability management, which will undoubtedly make contribution to the development of the ecommerce.
