Apple is introducing a new encryption protocol for iMessage designed to protect users from sophisticated attacks using quantum computers. New encryption protocols can protect users from scenarios where encrypted data is stored and later decrypted using quantum computers. iMessage is the second messaging platform known to introduce support for quantum-secure encryption (Signal’s PQXDH protocol introduced last year) while adding another layer of security to protect users in case their keys are compromised.

The company detailed its development of the new PQ3 protocol for iMessage on Wednesday, ahead of its rollout to supported iPhone, iPad, Mac, and Apple Watch models. According to Apple, PQ3 is a quantum-resistant encryption protocol designed to protect conversations from being compromised by attackers using quantum computers in the future.

Traditional public key cryptography, used in secure messaging services like WhatsApp, iMessage, and Signal, uses difficult math problems to protect users from powerful computers. However, powerful quantum computers are said to be able to solve these problems, meaning they could be used to compromise encrypted chats in the future, even if they don’t exist now.

Apple also highlights another challenge posed by quantum computers: the “harvest now, decode later” scenario. By storing the vast amounts of encrypted data available today, a capable attacker could gain access to the data at some point in the future, once a sufficiently powerful quantum computer can break the traditional encryption used to protect those messages.

iMessage is the second messaging platform to add support for quantum-secure encryption. Last year, Signal, widely known as the standard for encrypted messaging, announced the launch of a new PQXDH protocol that will protect users from quantum computers. Apple says its PQ3 encryption protocol goes one step further than PQXDH by continuously changing the post-quantum key. This limits the number of messages that can be exposed if the key is compromised.

According to Apple, the new PQ3 post-quantum encryption protocol is designed to protect users from existing and future adversaries and will be introduced from the launch of chat. This would need to be combined with the company’s existing encryption, with a hybrid design meaning attackers would need to defeat both traditional encryption and post-quantum primitives used to protect iMessage conversations.

To protect users in case their encryption keys are compromised, Apple says new post-quantum keys are sent periodically (rather than every message) to verify the size of these encrypted messages while still allowing users to access them. We provide service even when network conditions are poor.

The new PQ3 protocol has been reviewed by the company’s Security Engineering and Architecture (SEAR) team. It was also reviewed by a team led by Professor David Basin, Head of the Information Security Group at ETH Zürich, and Professor Douglas Stebila at the University of Waterloo. The company also said it contracted a third-party security consulting firm to independently evaluate the PQ3 source code and found no security issues.

Apple will provide support for PQ3 in future updates to iOS 17.4, iPadOS 17.4, macOS 14.4, and watchOS 10.4, and iMessage conversations on supported devices will automatically use a new quantum security protocol to encrypt messages sent and received on the device. He said he would start. platform. All supported conversations will be upgraded to post-quantum encryption protocols this year.
