The study gives an overview of the standardisation process of post-quantum cryptography (PQC). It also outlines proposals that system owners can implement to protect the confidentiality of their data against a quantum capable attacker: hybrid implementations that use a combination of pre-quantum and post-quantum schemes, and the mixing of pre-shared keys into all keys established via public-key cryptography.
