Apple Launches PQ3 for iMessage to Combat Future Quantum Computing Threats

The new post-quantum cryptographic protocol, PQ3, will be included in upcoming software updates, enhancing iMessage's security against potential quantum computing attacks.

Apple announces the introduction of PQ3, a post-quantum cryptographic protocol for iMessage, designed to protect against future quantum computing attacks.
PQ3 will be included in the upcoming updates to iOS 17.4, iPadOS 17.4, macOS 14.4, and watchOS 10.4, automatically upgrading iMessage conversations to the new encryption standard.
The new protocol combines Elliptic-Curve cryptography with post-quantum cryptography, requiring attackers to defeat both to compromise iMessage security.

The protocol has been externally reviewed and verified by academic research teams, with no security issues found.
