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 date, a number of VLR-GS schemes have been proposed under bilinear groups and lattices, while they have not yet been instantiated based on coding theory. ...
Our main contribution is to give a generic construction for the code-based group signature scheme with support of verifier-local revocation function. ...

Prior designs of attribute-based anonymous authentication schemes did not concentrate on providing full anonymity while at the same time holding public traceability. ...
Furthermore, based on TABAA, we propose the first attribute-based, decentralized, fully anonymous, publicly traceable e-voting, which enables voters to engage in a number of different voting activities ...

Our constructions involve new lattice-based tools for aggregating signatures and verifiable CCA2-secure encryption. ...
We present two lattice-based constructions of this new primitive, one with and one without opening capabilities for the group manager. ...
Thus, while our main focus is on anonymous attribute token schemes, we present as a corollary the first lattice-based, non-frameable group signature scheme with full anonymity. ...
