Apple is upgrading iMessage’s security layer to post-quantum cryptography in preparation for the potential threat of quantum computers breaking current encryption standards. The new protocol, called PQ3, combines Elliptic-Curve cryptography with post-quantum cryptography. Apple plans to refresh session keys for prior conversations and apply the PQ3 standard to all new iMessage conversations. This move comes as lawmakers consider online safety rules that could undermine encryption on messaging services.
Why do we care?
Fighting quantum computing security risks also wasn’t on my 2024 bingo card, but it’s a savvy strategic choice. Apple’s adoption of PQ3 could serve as a catalyst for other technology companies to prioritize upgrading their encryption methods to quantum-resistant standards.
IT service providers should begin exploring post-quantum cryptography solutions for their services and advise clients on the importance of adopting quantum-resistant encryption technologies to protect sensitive information and communications. Those wo are deliberate now will reap the benefits later. While I know your todo list is endless, put this one on it, and push your vendors to do the same.
