Apple readies iMessage for when quantum computers could break encryption
Apple is upgrading iMessage's security to post-quantum cryptography in an effort to avoid future "harvest now, decrypt later" attacks.
Apple announced today it is upgrading iMessage’s security layer to post-quantum cryptography, starting in iOS and iPadOS 17.4, macOS 14.4, and watchOS 10.4. “A sufficiently powerful quantum computer could solve these classical mathematical problems in fundamentally different ways, and therefore — in theory — do so fast enough to threaten the security of end-to-end encrypted communications,” Apple said in its blog post. The tech giant’s announcement comes as a time when lawmakers are looking to introduce online safety rules that run the risk of undermining encryption on messaging services.
