Title:
A Designer’s Guide to KEMs

Authors: Alexander W. Dent

Abstract:

A generic or KEM-DEM hybrid construction is a formal method of
combining a asymmetric and symmetric encryption techniques to give
an efficient, provably secure public-key encryption scheme. This
method combines an asymmetric KEM with a symmetric DEM, and each
of these components must satisfy their own security conditions. In
this paper we describe generic constructions for provably secure
KEMs based on lower level primitives such as one-way trapdoor
functions and weak key-agreement protocols.
