Attribute-based Signature Scheme

2008 International Conference on Information Security and Assurance (isa 2008), 2008
In real life, one requires signatures from people who satisfy certain criteria like that they should possess some specific attributes. For example, Alice wants a document to be signed by some employee in Bob's company. This employee must have certain attributes such as being part of the IT staff and at least a junior manager in the cryptography team or

Attribute-based Concurrent Signatures

Proceedings of the 6th International Conference on Information Engineering, 2017
This paper1 introduces the notion of attribute-based concurrent signatures. This primitive can be considered as an interesting extension of concurrent signatures in the attribute-based setting. It allows two parties fairly exchange their signatures only if each of them has convinced the opposite party possesses certain attributes satisfying a given ...

Attribute Based Sequential Aggregate Signature

2013 International Conference on Cloud Computing and Big Data, 2013
Attribute based signature (ABS) scheme is an important cryptographic primitive which provides a powerful way for user to control their privacy. However, the computational and storage cost of ABS is reasonable when the number of users involved in the system is huge.

Hierarchical Attribute-based Signatures

2021
An important yet challenging property for privacy-preserving ABS is revocation, which may be applied to signers or some of the attributes they possess. Existing ABS schemes lack efficient revocation of either signers or their attributes, relying on generic costly proofs.

Multi-authority Attribute-Based Signature

2011 Third International Conference on Intelligent Networking and Collaborative Systems, 2011
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 satisfying the policy.

Efficient Traceable Attribute-Based Signature

2014 IEEE 13th International Conference on Trust, Security and Privacy in Computing and Communications, 2014
In an Attribute-Based Signature (ABS) scheme, only users whose attributes satisfy the signing predicate can create valid signatures. Typically, ABS schemes require two properties: unforgeability and privacy. In this paper, we propose a new structure and syntax for Traceable Attribute-Based Signature (TABS), which has a good balance between privacy and ...

Accountable Authority Attribute-Based Signature

2013 Fourth International Conference on Emerging Intelligent Data and Web Technologies, 2013
Since attribute-based signature (ABS) was introduced by Guo et al. in 2008, considerable researches have been done. In an ABS scheme, the attribute authority (A-authority) generates the private key for any users, hence it has to be completely trusted.

Attribute-based signatures on lattices

The Journal of China Universities of Posts and Telecommunications, 2016
Abstract Because of its wide application in anonymous authentication and attribute-based messaging, the attribute-based signature scheme has attracted the public attention since it was proposed in 2008. However, most of the existing attribute-based signature schemes are no longer secure in quantum era.

Online/Offline Attribute Based Signature

2014 Ninth International Conference on Broadband and Wireless Computing, Communication and Applications, 2014
Attribute-based signature (ABS), which enables users sign messages with any predicate of their attributes issued from an attribute authority, is useful in many important applications such as anonymous authentication and attribute-based messaging systems.

Forward Secure Attribute-Based Signatures

2012
Attribute-Based Signatures (ABS) is a versatile primitive which allows an entity to sign a message with fine-grained control over identifying information. A valid ABS only attests to the fact that "A single user, whose attributes satisfy the predicate, has endorsed the message".
