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.

Attribute-Based Parallel Key-Insulated Signature [PDF]
Cybernetics and Information Technologies, 2015 To deal with the key-exposure protection problem in attribute-based signature systems, we extend the parallel key-insulated mechanism to attribute-based signature scenarios, and then introduce the primitive of an Attribute-Based Parallel Key-Insulated ...

Attribute based sanitizable signature scheme
Tongxin xuebao, 2013 Sensitive information in the document needs to be hidden in cloud computing environment, and attribute based sanitizable signature (ABSS) scheme was proposed to solve this problem. The ABSS scheme brings the character of sanitiz-able into ABS in order to

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 ...

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 ...
