Apple boosts iMessage security to fend off quantum computing attacks

The new security protocol has already been added to beta versions of iOS 17.4, iPadOS 17.4, macOS 17.4 and watchOS 10.4, which will roll out to all users in the coming weeks. — Bloomberg

Apple Inc is upgrading the security of its iMessage app, aiming to fend off a looming future threat: advanced quantum computing attacks.

The changes will be part of a new system called PQ3, Apple said on Wednesday (Feb 21). It’s a more advanced type of encryption that could thwart attacks from quantum computers - still-nascent technology that can perform calculations exponentially faster than traditional machines.
