Post-quantum secure group signature with verifier local revocation and backward unlinkability
AbstractGroup signature supports users to generate signatures on behalf of the group. Verifier local revocation (VLR) is an important method to revoke a misbehaving user in group signature, which has attracted many researchers’ attention. However, the ...
Highlights- We propose a new dynamic group signature scheme with backward unlinkability.
- A phased update of revocation tokens will provide higher security for signatures.
- The secret key size and signature size are independent of the number of ...
A Short Verifier-Local Revocation Group Signature Scheme with Backward Unlinkability
Previously Verifier-Local Revocation (VLR) group signature schemes from bilinear maps were proposed. In VLR schemes, only verifiers are involved in the revocation of a member, while signers are not. Thus, the VLR schemes are suitable for mobile ...
Group Signatures with Verifier-Local Revocation and Backward Unlinkability in the Standard Model
CANS '09: Proceedings of the 8th International Conference on Cryptology and Network SecurityGroup signatures allow users to anonymously sign messages in the name of a group. Membership revocation has always been a critical issue in such systems. In 2004, Boneh and Shacham formalized the concept of group signatures with <em>verifier-local ...
