On the Possibility of Constructing Meaningful Hash Collisions for Public Keys
It is sometimes argued (as in [6]) that finding meaningful hash collisions might prove difficult. We show that at least one of the arguments involved is wrong, by showing that for...

Group Signature Where Group Manager, Members and Open Authority Are Identity-Based
We present the first group signature scheme with provable security and signature size O(λ) bits where the group manager, the group members, and the Open Authority (OA) are all id...

Group Signature Schemes with Membership Revocation for Large Groups
Group signature schemes with membership revocation have been intensively researched. However, signing and/or verification of some existing schemes have computational costs of O(R)...
