Apple’s security team claimed to have achieved a breakthrough “That advances the art of end-to-end messaging.” With the upcoming releases 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, which aims to provide even stronger encryption and protection against sophisticated quantum computing attacks.
Such attacks aren’t a widespread threat today, but Apple is preparing for a future where bad actors will try to crack existing encryption standards and iMessage’s security layers with the help of massively powerful computers. Such scenarios may start appearing by the end of the decade, but experts agree The tech industry needs to start defending against them already.
“PQ3 is the first messaging protocol with what we call Level 3 security – this protocol provides security that is superior to all other widely deployed messaging apps,” the security team wrote. Yes, Apple came up with its own ranking system for messaging service security, and iMessage now stands alone at the top because of these latest PQ3 advancements.
In the company’s view, they’re enough to put Apple’s service above Signal, which recently launched More sophisticated security defenses, (For context, the current version of iMessage ranks as Level 1, along with older versions of WhatsApp, Viber, Line, and Signal.) “More than just replacing the existing algorithm with a new one, we broke the iMessage cryptographic protocol from the ground up. Rebuilt from. “To advance the state of the art in end-to-end encryption,” Apple wrote.
Apple says hackers can steal any encrypted data obtained today in the hope that it will be possible to break into it in several years once quantum computers become a realistic attack vector:
Although quantum computers with this capability do not yet exist, extremely well-resourced attackers can already prepare for their potential arrival by taking advantage of the huge reduction in modern data storage costs. The premise is simple: Such attackers can collect large amounts of today’s encrypted data and file it away for future reference. Even if they can’t decrypt any of this data today, they can retain it until they find a quantum computer that can decrypt it in the future, eliminating an attack scenario is called Harvest now, decrypt later,
You can read all the detailed details on the PQ3 in Apple’s blog post, which is a great example of the company’s focus on protecting user data. And as we have learned in recent months, Apple will not hesitate to turn off third parties — even well-intentioned people — who attempt to encroach on its iPhone-selling messaging platform by any means.
