Raptor: A Practical Lattice-Based (Linkable) Ring Signature

IACR Cryptology ePrint Archive, 2019
We present Raptor, the first practical lattice-based (linkable) ring signature scheme with implementation. Raptor is as fast as classical solutions; while the size of the signature is roughly 1.3 KB per user. Prior to our work, all existing lattice-based solutions are analogues of their discrete-log or pairing-based counterparts.

An Efficient Multilayered Linkable Ring Signature Scheme With Logarithmic Size for Anonymous Payment in Vehicle-to-Grid Networks

IEEE Transactions on Intelligent Vehicles, 2023
Vehicle-to-Grid (V2G) networks are potential solutions to addressing energy and environmental challenges, although security remains a key concern. For example, attackers may seek to obtain private information from frequent electricity/service exchanges ...

Based on Linkable Ring Signature Map Review Scheme for Zero-Trust Autonomous Vehicles

International Conference on Data Science in Cyberspace, 2023
The real-time map plays a vital role in the Internet of Vehicles (IoV) navigation. Compared with the existing map review, the real-time map review method is based on crowdsensing enabling faster data updates and shortening the map period from map ...

Revocable and Linkable Ring Signature

2020
In this paper, we construct a revocable and linkable ring signature (RLRS) scheme, which enables a revocation authority to revoke the anonymity of the real signer in linkable ring signature scheme under any circumstances. In other words, the revocability of RLRS is mandatory.

Linkable Ring Signature with Unconditional Anonymity

IEEE Transactions on Knowledge and Data Engineering, 2014
In this paper, we construct a linkable ring signature scheme with unconditional anonymity. It has been regarded as an open problem in [22] since 2004 for the construction of an unconditional anonymous linkable ring signature scheme. We are the first to solve this open problem by giving a concrete instantiation, which is proven secure in the random ...

Forward-Secure Linkable Ring Signatures

2018
We present the first linkable ring signature scheme with both unconditional anonymity and forward-secure key update: a powerful tool which has direct applications in elegantly addressing a number of simultaneous constraints in remote electronic voting.

Certificateless Linkable Ring Signature Scheme Based on SM2 Algorithm

ICON
Ring signatures are advanced cryptographic tools that authenticate messages while protecting the signer's identity, playing a crucial role in user privacy. However, traditional ring signatures allow a signer to generate multiple unique signatures for the

(Linkable) Ring Signature from Hash-Then-One-Way Signature

2019 18th IEEE International Conference On Trust, Security And Privacy In Computing And Communications/13th IEEE International Conference On Big Data Science And Engineering (TrustCom/BigDataSE), 2019
In this paper, we revisit the generic construction of ring signatures from hash-then-one-way type (Type-H) signatures proposed by Abe et al. (AOS) in 2004 and made the following contributions. First, we give a proof for the generic construction, in a strengthened security model.
