使用双线性对构造基于身份的不可否认签名(英文)

Identity-based undeniable signatures from bilinear pairings

使用椭圆曲线上的映射对构造基于身份的确认签名(也是不可否认签名),最早由Han S等人提出.然而, Zhang F等人证明Han S的签名是不安全的.本文对Han S的方案进行了修改,构造了使用椭圆曲线上映射对和零知识证明的基于身份的不可否认签名方案,且证明了它是安全的.

Identity-based confirmer signatures from pairings over elliptic curves, also known as identity-based undeniable signatures, were first proposed by Han S et al. However, Zhang F et al showed that these signature schemes are insecure. This paper proposes a modified signature scheme based on zero-knowledge, and proves its security.
