Group Signatures with Verifier-Local Revocation and Backward Unlinkability in the Standard Model
Group 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...

Fully Robust Tree-Diffie-Hellman Group Key Exchange
We extend the well-known Tree-Diffie-Hellman technique used for the design of group key exchange (GKE) protocols with robustness, i.e. with resistance to faults resulting from poss...
