In this paper the authors study strong adaptive corruption security definitions for Authenticated Key Exchange (AKE) protocols. Many recent protocols for Authenticated Key Exchange have been proven correct in the CK01 or eCK security model. The new model is suggested to be at least as strong as previous models for authenticated key exchange protocols. However, they observe that there are several kinds of attacks on existing AKE protocols that beyond the current class of security definitions which further reveal the shortcomings in security proofs in related AKE security models, in particular concerning the protocols under eCK model.
