Apple is taking a proactive approach to the looming threat of quantum computers by implementing post-quantum encryption in its iMessage platform.
The latest update, iOS and iPad OS 17.4, will incorporate PQ3, Apple’s post-quantum cryptographic protocol. This significant upgrade aims to ensure the security of iMessage communications, providing protection against potential quantum-based attacks.
Quantum computing poses a serious challenge to current encryption methods, as it has the potential to easily crack existing encryption algorithms. While practical quantum computers are not yet widely available, their development is being pursued by governments and tech companies worldwide. In response, Apple is taking steps to bolster the security of its messaging platform against future threats.
By rebuilding the iMessage cryptographic protocol from the ground up, Apple’s PQ3 implementation aims to replace existing encryption protocols entirely by the end of the year. Users can benefit from this enhanced security simply by updating their operating systems. PQ3 generates new post-quantum encryption keys for secure communication and adapts to changing quantum threats, ensuring ongoing protection.
Apple’s adoption of post-quantum encryption follows similar moves by other companies. Signal, a popular encrypted messaging app, introduced post-quantum algorithms in September, while Proton is developing quantum-safe PGP encryption for widespread use. These efforts reflect the growing recognition of the need for quantum-resistant cryptographic solutions.
To maintain the highest level of security, Apple combines its existing elliptic curve cryptography (ECC) with post-quantum protections in a hybrid design. PQ3 has undergone external assessment by a third-party security company and received scrutiny from academic research groups. The protocol has demonstrated strong security guarantees against network adversaries with quantum computing capabilities.
While the development of practical quantum computers remains uncertain, deploying post-quantum encryption now helps mitigate the risk of “harvest now, decrypt later” attacks. Adversaries may collect encrypted data with the intention of decrypting it once quantum technologies advance. By implementing post-quantum encryption, Apple aims to limit the potential impact of such attacks.
With this update, Apple reinforces its commitment to user privacy and security. By incorporating post-quantum encryption into iMessage, Apple ensures that billions of messages sent daily remain protected, even in the face of evolving quantum threats.
The integration of PQ3, Apple’s post-quantum cryptographic protocol, into iOS and iPadOS 17.4 represents a pivotal step towards bolstering the security of iMessage communications. With the looming threat of quantum-based attacks on traditional cryptographic methods, Apple’s proactive approach not only safeguards user data but also serves as a validation of the urgency surrounding post-quantum cryptography (PQC).
This development serves as a resounding “wakeup call” to the world, highlighting the critical importance of addressing the quantum threat sooner rather than later. Companies and individuals alike must recognize the evolving landscape of cybersecurity and prioritize implementing solutions capable of withstanding quantum computing advancements.
In this context, solutions like IronCAP emerge as indispensable tools for navigating the post-quantum journey. By leveraging IronCAP’s expertise in post-quantum cryptography, users can fortify their digital communications and data against the unprecedented challenges posed by quantum computing.
Apple’s bold move underscores the necessity for proactive measures in the face of emerging technological threats, paving the way for a more secure digital future.

We at IronCAP™ have been trying to educate businesses and individuals that Q-day (the day the first quantum hack is publicly recognized) is around the corner and everybody needs to gear up. Nation states and governments are already at it, how about you? To learn more, visit www.ironcap.ca.
IronCAP™ is our latest innovation for the post-quantum cybersecurity. This patent-protected, post-quantum cryptographic system is based on the Goppa Code-based cryptographic technology. It has embedded our proprietary subclass of (L, G) making it not only more secured but also has faster cryptographic operations (key generation, encryption, decryption) than the traditional Goppa Code-based technology (McEliece). We are offering a live demonstration for the general public to try and experience the strength of IronCAP™ post-quantum encryption easily. To learn more, visit www.ironcap.ca.
