"Apple Introduces Quantum-Proof Encryption for iMessage Security"

Apple has introduced a significant security upgrade for iMessage called PQ3 to protect against quantum computers, with the feature already available in the iOS 17.4 beta. Users can install the beta to get the quantum security or wait for the public release in early March, with the upgrade expected to automatically roll out to iMessage conversations over time. The PQ3 upgrade is crucial in safeguarding against future quantum computer-based attacks, addressing vulnerabilities like "Harvest Now, Decrypt Later" and enhancing encryption protection.
