Apple is introducing an enhancement to its iMessage texting platform aimed at bolstering its resistance against potential decryption by emerging quantum-based encryption-breaking technologies.

The new protocol, named PQ3, signifies the proactive stance of U.S. technology companies in preparing for potential advancements in quantum computing that might render current communication protection methods ineffective.
In a blog post published on Wednesday, Apple explained that the PQ3 protocol is not just a mere replacement for an existing algorithm but rather a comprehensive reconstruction of the iMessage cryptographic protocol. This overhaul is set to replace the current protocol in all supported conversations throughout the course of this year.
The California-based company asserts that its encryption algorithms are cutting-edge and, to date, no evidence has been found of any successful attacks on them. However, there is growing concern among government officials and scientists regarding the potential impact of quantum computers – advanced machines leveraging the properties of subatomic particles—that could significantly and abruptly weaken existing encryption protections.
Apple’s blog highlights that PQ3 incorporates a new and overlapping set of technical safeguards designed to minimize this vulnerability window.
The United States and China are actively preparing for this anticipated moment, often referred to as “Q-Day.” Both nations are heavily investing in quantum research and exploring new encryption standards, specifically post-quantum cryptography, to stay ahead of potential vulnerabilities.
This race involves substantial financial commitments and has led to accusations between Washington and Beijing about intercepting large volumes of encrypted data in readiness for Q-Day, a strategy colloquially known as “catch now, crack later.”
The U.S. cyber watchdog agency, the Cybersecurity and Infrastructure Security Agency, emphasized the importance of early planning in a 2022 advisory, stating that cyber threat actors might target data currently in existence that will necessitate protection in the future.
