iMessage with PQ3: The new state of the art in quantum-secure messaging at scale
https://security.apple.com/blog/imessage-pq3/

Today we are announcing the most significant cryptographic security upgrade in iMessage history with the introduction of PQ3, a groundbreaking post-quantum cryptographic protocol that advances the state of the art of end-to-end secure messaging. With compromise-resilient encryption and extensive defenses against even highly sophisticated quantum attacks, PQ3 is the first messaging protocol to reach what we call Level 3 security — providing protocol protections that surpass those in all other widely deployed messaging apps. To our knowledge, PQ3 has the strongest security properties of any at-scale messaging protocol in the world.

PQ, "Post-Quantum". Er is in ieder geval een goede marketeer op gezet. 

Tweakers heeft er ook al een bericht over:
