Scalable protocol for cross-domain group password-based authenti...

Cross-domain password-based authenticated key exchange (PAKE) protocols have been studied for many years. However, these protocols are mainly focusing on multi-participant within a single domain in an open network environment. This paper proposes a novel approach for designing a cross-domain group PAKE protocol, that primarily handles with the setting of multi-participant in the multi-domain. Moreover, our protocol is proved secure against active adversary in the Real-or-Random (ROR) model. In o
