Wake-up Call from Apple for Post-Quantum Threats!!

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.

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.

With the looming threat of quantum-based attacks on traditional cryptographic methods, Apple’s proactive approach to incorporate post-quantum encryption into iMessage serves as a resounding “wake-up 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.

You need to act now!

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, governments and Apple are already at it, how about you? To learn more, visit

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
