有效的ABS Signature证明了这样一个事实:“属性满足谓词的单个用户背书了消息”。在这种非正式的安全保证中,我们强调“单一”这个词;ABS签名,就像在大多数基于属性的系统中一样,要求串通方不能将他们的属性集中在一起。而且,即使在有其他签名的情况下,属性基签名也不能透露更多关于属性的声明。
An attribute-based digital signature system comprises a signature generation unit (1) for signing a message (m) by generating a signature (蟽) based on a user secret key (SK) associated with a set of user attributes, wherein the signature generation unit (1) is arranged for combining the ...
可追踪的基于属性的签名(Traceable attribute-based signature)是一种有效的密码学工具,在一些条件下可以在追踪真实签名者的同时保护真实签名者的身份。可追踪的基于属性的签名继承了基于属性签名的优点,每个签名者都可以对任何消息进行签名,并对身份信息进行细粒度访问控制(fine-grained access control)。 基于属性的签名(...

Attribute-based signature (ABS) is a new cryptographic primitive, in which a signer can sign a message with his attributes, and the verifier can only known whether the signer owns attributes satisfying his policy. Moreover, the signature cannot be forged by any user not having attributes satisfy...
This paper addresses the open problem of designing attribute-based signature (ABS) schemes with constant number of bilinear pairing operations for signature verification or short signatures for more general policies posed by Gagné et al. in Pairing 2012. Designing constant-size ABS for expressive acce...
Attribute-based signature (ABS) assures the verifier that the message is endorsed by a signer whose attributes satisfy the claimed attribute policy (predicate); thus, it can provide identity authentication with privacy preservation in scenarios like anonymous communication and access control. However, we...
