Group Signature with Verifier-Local Revocation Based on Coding Theory
2021
Security and Communication Networks
Preserved Fulltext
Group signature with verifier-local revocation (VLR-GS) is a special variant of revocable group signature that not only allows a user to anonymously sign messages but also only requires the verifiers to ...
To obtain the scheme, we first introduce a new code-based Stern-like interactive zero-knowledge protocol with member revocation mechanism based on syndrome decoding problem. ...
Our main contribution is to give a generic construction for the code-based group signature scheme with support of verifier-local revocation function. ...

Group signatures and ring signatures are the two leading competitive signature schemes with a rich body of research. Both group and ring signatures enable user anonymity with group settings. ...
We selected many papers that discuss balancing user tracing and anonymity in group and ring signatures. ...
In group signature schemes with verifier-local revocation [29, 39, 41, 89] , a token determines the users' revocation status. ...
