基于聚合签名的多方合同签署协议
DOI: 10.13190/jbupt.201102.8.sunyb, PP. 8-11

Abstract:
利用无限制的聚合签名方案和公钥密码系统广播协议，提出了一个新的安全多方合同签署协议.合同签署协议利用广播协议实现签署者之间消息的分发，利用无限制的聚合签名方案实现签署者之间合同的签署，执行过程分为2个阶段签署者进行消〖JP9〗息-〖JP〗凭证聚合签名的交换；广播发送合同签名.如果执行过程中发生争议，签署者要求仲裁者介入，在保证其公平性的基础上结束协议.该协议满足不可伪造性、不透明性、可提取性和公平性，且随着签署者人数的增加，消息交互次数呈线性增长，效率较高.
