Key Agreement in the Standard Model
Georg Lippold, Juan Gonz · 2010
We show how to construct a certicateless key agreement protocol from the certicateless key encapsulation mechanism introduced by Lippold et al. (2009a) in ICISC 2009 using the Boyd et al. (2008) protocol from ACISP 2008. We introduce the CanettiKrawczyk (CK) model for certicateless cryptography, give security notions for Type I and Type II adversaries in the CK model, and highlight the dierences to the existing e 2 CK model discussed by Lippold et al. (2009b). The resulting CK model is more relaxed thus giving more power to the adversary than the original CK model.
