Identity-Based Linkable Ring Signature Scheme

IEEE Access, 2019
A ring signature is an anonymous signature that implements both the authentication of the message and the anonymity of the signer. In a “normal” ring signature scheme, the same signer can generate multiple ring signatures, but the verifier ...

Certificateless Linkable Ring Signature Scheme

IEEE Access, 2020
Ring signature is an anonymous signature that both authenticates the message and protects the identity information of the signer. It is suitable for scenarios such as anonymous network access, online auctions, etc.

Physical Ring Signature

Fun with Algorithms
Ring signatures allow members of a group (called ring) to sign a message anonymously within the group, which is chosen ad hoc at the time of signing (the members do not need to have interacted before). In this paper, we propose a physical version of ring signatures.

Research Progress and Prospect of Ring Signatures [PDF]

Jisuanji kexue yu tansuo, 2023
As a special group signature, ring signature has been widely used in anonymous voting, anonymous deposit and anonymous transaction because it can not only complete the signature without the cooperation of ring members, but also ensure the anonymity of ...

Secure E-Voting Protocol Based on SM9 Blind Signature and Ring Signature [PDF]

Jisuanji gongcheng, 2023
To solve the problems of anonymity，public verifiability，ballot collision，and forgery in the process of e-voting，an anonymous public verifiable e-voting system protocol design scheme is proposed based on SM9 algorithm.This scheme constructs an identity ...

Ring Signature Scheme of Programmable Hash Function on Lattices [PDF]

Jisuanji gongcheng, 2020
To address the problem that the length of signature and key is too long in traditional ring signature schemes on lattices,this paper proposes an improved ring signature model of Programmable Hash Function(PHF) on lattices.The MP12 trapdoor function is ...

Lattice-Based Logarithmic-Size Non-Interactive Deniable Ring Signatures

Entropy, 2021
Deniable ring signature can be regarded as group signature without group manager, in which a singer is capable of singing a message anonymously, but, if necessary, each ring member is allowed to confirm or disavowal its involvement in the signature via ...

An Improved Scheme for PBFT Blockchain Consensus Algorithm Based on Ring Signature [PDF]

Jisuanji gongcheng, 2019
The alliance chain is a kind of blockchain that allows authorized nodes to join in the network.However,when the network condition is poor,the nodes will join and exit dynamically.Therefore,on the basis of ring signature theory,ElGamal digital signature ...
