摘要：
We extend the concept of key encapsulation to the primitives of identity-based and certificateless encryption. We show that the natural combination of ID-KEMs or CL-KEMs with data encapsulation mechanisms results in encryption schemes that are secure in a strong sense. In addition, we give generic constructions of ID-KEMs and CL-KEMs that are provably secure in the random oracle model.
