Apple’s security team claims to have achieved a breakthrough “that advances the state of the art of end-to-end messaging.” With the upcoming release of iOS 17.4, iPadOS 17.4, macOS 14.4, and watchOS 10.4, the company is bringing a new cryptographic protocol called PQ3 to iMessage that it purports to offer even more robust encryption and defenses against sophisticated quantum computing attacks.

Such attacks aren’t yet a broad threat today, but Apple is preparing for a future where bad actors try to unwind current encryption standards and iMessage’s security layers with the help of massively powerful computers. Such scenarios could start playing out by the end of the decade, but experts agree that the tech industry need to start defending…
