Abstract :
In this paper, we present a two-party attribute-based authenticated key exchange scheme for a wide class of relations, which are specified by non-monotone access structures combined with inner-produce relations. We prove the security of our scheme under the decisional linear (DLIN) assumption, without random oracle, in our ABCK model, which is a natural extension of the CK model.
