Apple Debuts PQ3: Groundbreaking Post-Quantum Cryptographic Upgrade for iMessage
Summary:
Apple introduces PQ3, a significant security upgrade for iMessage in iOS 17.4, making Apple one of the few providers of post-quantum cryptography for messaging. With this new protocol, Apple claims to be the first to reach "level 3" encryption. The move is a response to the imminent threat of quantum computing, which could potentially break traditional encryption methods. Current quantum computing systems don't possess this capability, but rapid advancements in quantum technology have prompted many entities to prepare for future threats. The approach aims to allow 'good actors' to safeguard their data using advanced cryptographic techniques against potential future security risks.
On February 21, Apple introduced PQ3, an algorithm that provides an unprecedented leap in the cryptography security of iMessage, for iOS 17.4. This new upgrade places Apple as one of the select few providers that offer post-quantum cryptography for messaging. Even though Signal unfurled a similar update touted as "quantum-resistant" in September 2023, Apple claims the distinction of being the first to achieve "level 3" encryption.

In the words of the Cupertino-based tech giant:
"PQ3 stands out as the pioneer messaging protocol to hit what we term as Level 3 security. This furnishes protocol safeguards that are superior to those found in other widely used messaging apps. As far as we are concerned, no other large-scale communication protocol rivals the robust security traits of PQ3."
Regarding post-quantum messaging, Apple's iMessage application offered end-to-end encryption from its inception, initially resorting to RSA encryption. In 2019, the company transitioned to Elliptic Curve cryptography (ECC). As of now, neutralizing this encryption is deemed impossible, given the considerable time and computational power demanded. Yet, the specter of quantum computing appears increasingly imminent.
In theory, an adequately powerful quantum computer could easily decipher today's encryption protocols. Even though no current quantum computing structures possess this capacity, the swift developmental progress has prompted governments and corporations globally to initiate contingency measures. The overarching plan is to devise post-quantum cryptographic techniques in advance, thereby securing the data of beneficial entities like hospitals and banks against advanced malicious threats.
Quantum-safe encryption does not have a concrete launch timeline for quantum machines capable of breaching traditional cryptography. While IBM assumes a turning point in quantum computing by 2029, QuEra, an MIT/Harvard spinoff, projects a 10,000-qubit error-corrected system by 2026.
On the flip side, malevolent entities are not poised to hold off on their assaults until they acquire quantum computers. Several have resorted to unauthorized data procurement and hoarding with future decryption intentions, known as a HNDL attack (harvest now, decrypt later).
