Invisible Designated Confirmer Signatures without Random Oracles

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.
