Secure communication is gained by combining encryption with authentication. In real-world applications encryption commonly takes the form of KEM-DEM hybrid encryption, which is combined with ideal authentication. The pivotal question is how weak the employed key encapsulation mechanism (KEM) is allowed to be to still yield universally composable (UC) secure communication when paired with symmetric encryption and ideal authentication. This question has so …
