Abstract: Designing non-committing encryptions tolerating adaptive adversaries is a challenging task. In this paper, a simple implementation of non-committing encryptions is presented and analyzed in the strongest security model. We show that the proposed non-committing encryption scheme is provably secure against adaptive adversaries in the universally composable framework assuming that the decisional Diffie-Hellman problem is hard.
