Quantum computers capable of cracking today’s encryption don’t exist yet. But the race to defend against them just produced its first tangible product for your pocket.
STMicroelectronics, the Franco-Italian semiconductor giant traded on the NYSE under STM, has launched the ST54M, a mobile chip it calls the first in the world to include a dedicated hardware accelerator for post-quantum cryptography. Announced on June 24, the chip crams an NFC controller, an embedded secure element (eSE), eSIM capability, and that PQC accelerator onto a single piece of silicon.
What the chip actually does
The more immediate risk has a name: harvest now, decrypt later. Bad actors intercept and stockpile encrypted data today, betting that quantum computers will eventually let them crack it open. The ST54M is designed to shut that strategy down before it pays off.
The chip supports two NIST-standardized algorithms. ML-KEM handles key encapsulation, which is the process of securely exchanging cryptographic keys between parties. ML-DSA manages digital signatures, verifying that data hasn’t been tampered with.
The practical applications span contactless payments, digital identity verification, transit ticketing, and access control.
On the hardware side, the chip offers up to 4.5 MB of nonvolatile memory and improved RF performance designed to work with flexible antenna configurations. That memory figure matters because post-quantum algorithms tend to be significantly more resource-hungry than their classical counterparts, requiring larger key sizes and more computational overhead.
Certification timeline and production plans
STMicroelectronics has already started shipping samples of the ST54M. The company expects to secure Common Criteria 2022 EUCC and EMVCo certifications by July 2026, with volume production planned around the same timeframe.
Common Criteria certification is a globally recognized security evaluation standard used by governments and enterprises. EMVCo certification is the seal of approval from the consortium behind chip-based payment card standards, backed by Visa, Mastercard, and the other major card networks.
The ST54M builds on STMicroelectronics’ earlier work in post-quantum cryptography. The company released its X-CUBE-PQC software libraries around October 2025, providing developers with tools to start integrating quantum-resistant algorithms into their applications. Software implementations of PQC run slower and consume more power than hardware-accelerated versions, a critical consideration for battery-powered mobile devices.
What this means for investors and the broader market
NIST finalized its first set of post-quantum cryptographic standards in 2024, and governments from the US to the EU have been issuing guidance urging organizations to begin their migration to quantum-resistant systems.
