"Apple Enhances iMessage Security with Quantum-Proof Encryption"

Apple is upgrading iMessage's security to post-quantum cryptography in anticipation of quantum computers being able to break today's encryption standards. The new PQ3 protocol combines Elliptic-Curve cryptography with post-quantum cryptography, and will refresh session keys for prior conversations. This move aims to protect against future quantum encryption attacks, as quantum computers could potentially decrypt today's encrypted data. The announcement comes amidst discussions about online safety rules and efforts by other companies, such as Meta and Signal, to enhance encryption protection in messaging services.
