Hybrid post-quantum cryptography is a cautious approach that aims to guard against the threat posed by the quantum computer, through the simultaneous use of Post- Quantum (PQ) and classical (i.e. pre-quantum) cryptosystems, in case the post-quantum schemes used would turn out to be insecure.


Regarding the hybridization of Key Encapsulation Mechanisms (KEMs), most recent studies focus on how to safely combine the symmetric keys output …
