In this paper we consider commitment schemes that are secure against concurrent man-in-the-middle (cMiM) attacks. Under such attacks, two possible notions of security for commitment schemes have been proposed in the literature: concurrent non-malleability with respect to commitment and concurrent non-malleability with respect to decommitment (i.e., opening… (More)
