In this work we introduce attribute-based signatures (ABS). Signatures in an ABS scheme describe a message and a predicate over the universe of attributes. A valid ABS signature attests to the fact that “a single user, whose attributes satisfy the predicate, endorsed the message.” We emphas...
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。
Attribute-based signcryption (ABSC) can fulfill the functionality of attribute-based signature (ABS) and attribute-based encryption (ABE) in a logical step. Depending on whether the access policy is embedded in the keys or ciphertexts, ABS and ABE are generally divided into two types: key ...
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(...
Based on this consideration, an attribute-based signature on lattices, which could resist quantum attacks, is proposed. This scheme employs “bonsai tree” techniques, and could be proved secure under the hardness assumption of small integer solution problem.Xian-ping Mao 毛贤平...

PrivacySecurity analysisAttribute-based signature (ABS) enables a signer, who possesses a set of attributes, to anonymously sign a message with respect to some signing policy. A recipient of the signature can just ensure that a signer owing attributes that satisfy the signing policy has...
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 schemes (ABS) constitute important and powerful primitives when it comes to protecting the privacy of the user's identity and signing information. More specifically, ABS schemes provide the advantage of anonymously signing a message once a given policy is satisfied. As oppose...
