Attribute-Based Blind Signature Scheme Based on Elliptic Curve Cryptography
IEEE Access, 2022 Blind signature is a special digital signature that allows the signer to sign a document without knowing its content. However, in many situations, multiple people need to blindly sign messages.

multi-authority Attribute-based Signature
工程科学与技术, 2011 :In real life, many attributes of a user are monitored by a single authority, which will inevitably increase its workload and reduce its efficiency. In this paper, the proposed multi-authority Attribute-based Signature scheme is that many attributes are ...

Attribute-Based Signature with Message Recovery
Lecture Notes in Computer Science, 2014 We present a new notion called the attribute-based signature with message recovery. Compared with the existing attribute-based signature schemes, an attribute-based signature with message recovery scheme does not require transmission of the original message to verify the validity of the signature, since the original message can be recovered from the ...

Attribute-based ring signature scheme with constant-size signature
IET Information Security, 2010 An attribute-based ring signature scheme with constant size and constant number of pairings computation is proposed. The signer signs messages by using a subset of its attributes. All the users who possess the subset of these attributes form a ring. It requires that anyone cannot tell who generates the signature in this ring. Furthermore, anyone out of

A Delegation Attack Method on Attribute-Based Signatures and Probable Solutions
Mathematics, 2022 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 ...
