    abstract =  {PQ/T Hybrid Key Encapsulation Mechanisms (KEMs) combine "post- quantum" cryptographic algorithms, which are safe from attack by a quantum computer, with "traditional" algorithms, which are not. CFRG has developed a general framework for creating hybrid KEMs. In this document, we define concrete instantiations of this framework to illustrate certain properties of the framework and simplify implementors' choices.},
