What are the steps I need to take to achieve quantum safe security?

First let me explain what a Quantum Security is :

Quantum cryptography, also called quantum encryption or security is known as quantum mechanics to encrypt messages in a way that it is never read by anyone outside of the intended recipient.

It’s the best way of encrypting any milliary grade informations that no regular computer or quantum computer could decrypt except if they have the encrypting keys.

Now back to our main subject on steps to achieve quantum save security.

✓ Use full-entropy random numbers for all cryptographic purposes. These are necessary for all quantum-safe cryptography.

✓ Use longer keys for symmetric encryption: these will need to be at least twice as long as those used today, to allow similar protection.

✓ Ensure your key managers are crypto-agile, i.e. able to work with longer keys and new quantum resistant algorithms.

✓ Explore key exchange solutions such as quantum key-distribution (QKD) and keep abreast of NIST’s selections of new quantum-resistant encryption algorithms (QRA).

✓ Use secure links between key management nodes, protected by QKD and/or quantum resistant algorithms.
