Most ID-based AKA protocols require that all parties are members of the same domain. In this paper, we present a new ID-based AKA protocol between members of distinct domains, which makes use of a new technique called twin Diffie-Hellman problem proposed by Cash, Kiltz and Shoup. It is inspired on a new ID-based two-party authenticated key exchange protocol proposed by Hai Huang and Zhenfu Cao. We show that our scheme is secure in the enhanced Canetti-Krawczyk (eCK) model, which better supports the adversary's queries than previous AKA models. To the best of our knowledge, our scheme is the first IDbased AKA protocol between members of distinct domains provably secure in eCK model.
