: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。
: An ElGamal Ordered Multiple Digital Signature Scheme is designed based on DSA (American Digital Signature Standard Algorithm). Allowing multiple parties to order a certain document sequentially and signing them into a group signature. The program can detect and prevent fraudulent acts by dishonest signers. Because of simplifying the interface between signers, reducing communication costs, effectively avoiding the signature deadlock, so more secure and practical.
