ETSI TS 104 015 V1.1.1 Cyber Security (CYBER); Quantum-Safe Cryptography (QSC); Efficient Quantum-Safe Hybrid Key Exchanges with Hidden Access Policies

A technical specification describing how to build and instantiate key encapsulation mechanisms whose access policies stay hidden, with key privacy resting on two hybridised assumptions: classical Computational Diffie-Hellman and post-quantum Learning With Errors. Because both underlying problems would have to be solved to expose an encapsulated key, the design aims to stay secure if either the classical or the post-quantum component fails.
