White-box Traceable Attribute Signature Scheme [PDF]

open access: yesJisuanji gongcheng, 2017
Attribute-based Signature(ABS) protocol has the property of anonymity,and its private keys are not band to identities.Malicious users might make use of this to leak their private keys for financial benefits.Therefore,this paper proposes a traceable ...

Attribute-Based Signatures [PDF]

open access: yes, 2011
We introduce Attribute-Based Signatures (ABS), a versatile primitive that allows a party to sign a message with fine-grained control over identifying information. In ABS, a signer, who possesses a set of attributes from the authority, can sign a message with a predicate that is satisfied by his attributes.

Decentralized Attribute-Based Signatures [PDF]

open access: yes, 2013
We present the first decentralized multi-authority attribute-based signature (DMA-ABS) scheme, in which no central authority and no trusted setup are required. The proposed DMA-ABS scheme for a large class of (non-monotone) predicates is fully secure (adaptive-predicate unforgeable and perfectly private) under a standard assumption, the decisional ...

Anonymous trust management scheme of VANET based on attribute signature

open access: yes网络与信息安全学报, 2023
Trust management mechanisms can solve the authenticity assessment problem of messages and establish trust between communication entities in the VANET.However, current trust management schemes lack an effective privacy protection mechanism, leading to ...

Blockchain Supervisable Privacy Protection Scheme Based on Group Signature and Attribute Encryption [PDF]

open access: yesJisuanji gongcheng, 2022
The decentralization of blockchain technology and difficulty of data tampering provide it with obvious advantages in traceability.Traceability systems based on blockchain can solve information island, low sharing degree, and data tampering problems in ...

Decentralized Traceable Attribute-Based Signatures [PDF]

open access: yes, 2014
We provide a formal security model for traceable attribute-based signatures. Our focus is on the more practical case where attribute management is distributed among different authorities rather than relying on a single central authority. By specializing our model to the single attribute authority setting, we overcome some of the shortcomings of the ...

Secure Outsourced Attribute-Based Signatures [PDF]

open access: yesIEEE Transactions on Parallel and Distributed Systems, 2014
Attribute-based signature (ABS) enables users to sign messages over attributes without revealing any information other than the fact that they have attested to the messages. However, heavy computational cost is required during signing in existing work of ABS, which grows linearly with the size of the predicate formula.

Attribute-Based Parallel Key-Insulated Signature

open access: yesCybernetics 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 ...
