摘要 为拓展指定证实者签名的应用范围,将基于属性和指定证实者签名相结合,并引入去中心的概念,研究了去中心基于属性指定证实者签名,给出其正式定义和安全模型,并构造一个具体方案。方案主要基于Cramer等人的证据隐藏证明协议,选择Schnorr协议作为其基础∑协议,使用Shamir门限方案作为其秘密分享方案,再使用Fiat-Shamir转换得到一个门限签名方案,然后再进行指定证实、防共谋和去中心化处理,最后得到一个无双线性对的去中心基于属性指定证实者签名方案,并在随机预言机模型下证明其安全性。方案可应用于多用户环境下的电子投标等实用场景。

英文摘要 To expand the application field of designated confirmer signature, this paper introduced a concept of decentralized attribute-based designated confirmer signature(DABDCS) by combing the concepts of attribute-based and decentralization with designated confirmer signatures. It presented the formal definition and security model of DABDCS, and proposed a concrete scheme. The scheme was based on Cramer <i>et al</i>. 's witness hiding protocol, in which Schnorr identification was chosen as its basis ∑ protocol, and Shamir threshold scheme as its secret sharing scheme. Based on the threshold signature scheme, it proposed a decentralized attribute-based designated confirmer signature scheme without bilinear pairings, and proved its securities under the random oracle model. The proposed scheme can be applied to multiple-party communication environments, such as electronic bidding and so on.
