Welcome to the resource topic for 2006/325

Title:
Invisible Designated Confirmer Signatures without Random Oracles

Authors: Victor K. Wei

Abstract:

We construct the first O(1)-size designated confirmer signatures (DCS) with security in the state-of-the-art model of Camenisch and Michels, Eurocrypt 2000, without random oracles. In particular, we achieve the security notion called the “invisibility of signature” therein.
