摘要: 基于身份、门限和盲是当代密码学领域3个重要的概念。该文结合已有盲签名和门限签名,提出一种利用双线性对实现基于身份的门限盲签名的构造方案。分析结果表明,与已有基于身份的数字签名相比,该方案易于实现,且保留了门限签名和盲签名的性质。

关键词: 基于身份, 门限盲签名, 双线性对

Abstract: Identity-based, threshold and blindness are three important concepts in current cryptology. This paper presents an identity-based threshold blind signature scheme from current blind signatures and threshold signatures by bilinear pairing. Compared with current identity-based signature schemes, this scheme is easier to carry out. It holds blindness and threshold properties.

Key words: identity-based, threshold blind signature, bilinear pairing
