Apple has recently announced a major security update for iMessage that’ll provide protection against quantum computers. As iOS is being released for all users, Apple has revealed a cryptographic update for iMessage named PQ3. This update is marked as “most significant.” The latest iMessage quantum security update is available for iPhone in iOS 17.4 beta. This article will provide a guide for how you can get iMessage quantum security update on your iPhone, iPad, Mac, and Apple watch.
To enable the update on your device, follow these instructions.
Or you can wait till iOS 17.4 will be released for public (until March).
As elaborated by Apple, there’ll be automatic “ramping up” of iMessage. As the conversations will be switched to post-quantum encryption protocol. However, it requires a device to be running iOS 17.4 at both ends of iMessage. As revealed by Apple, this PQ3 iMessage quantum security upgrade will take over the current protocol within all supported conversations during this year.
It is critical to stay ahead of upcoming quantum computer-based threats. One of the current risks is the “Harvest Now, Decrypt Later” strategy. Threat actors take data now and gain access to it when more potent machines become available later to break current encryption. PQ3 (iMessage quantum security) offers further protection against this vulnerability.
