We extend the concept of key encapsulation mechanisms to the primitives of ID-based and certificateless encryption. We show that the natural combination of ID-KEMs or CL-KEMs with data encapsulation mechanisms results in encryption schemes which are secure in a strong sense. In addition, we give generic constructions of ID-KEMs and CL-KEMs, as well as specific instantiations, which are provably secure.
