摘要： :以美国数字签名标准算法DSA 为基础设计了一种ElGamal型有序多重数字签名方案。允许多方顺序地对某一份文件进行签名,然后把它们构成一份群体签名。该方案可以检测和防止不诚实签名者的欺骗行为。由于简化了签名者之间的接口,减少了通信成本,有效地避免了签名死锁,因而更具安全性和实用性。

Abstract: In this paper ,an applied scheme for seqential multisignature based on USAs digital signature standard DSA is presented .It allows multiple signers to sign the same message seperately and all of their signatures are then combinated into a multisignature . It can prevent some dishonest participants from cheating others .Because of its simple interface between two signers ,it has lower communication casts compared to other digital signature scheme , therefore,it is more safe and practical.
