STMicroelectronics Launches First Mobile Chip With PQC Hardware Accelerator

STMicroelectronics has unveiled the ST54M, the first mobile chip integrating a dedicated hardware accelerator for post-quantum cryptography, a move designed to future-proof mobile devices against evolving security threats. Unlike software-based approaches, this dedicated accelerator promises a performance advantage as developers prepare for the transition to quantum-resistant algorithms. The single-die design consolidates this PQC capability with Near Field Communication, a secure element, and embedded SIM functionality, potentially streamlining device complexity for manufacturers supporting applications from contactless payments to digital car keys. “With ST54M, we are extending our mobile-convergence platform to help customers address evolving security challenges while supporting the rich set of services users now expect from their devices,” said David Richetto, Connected Security Group VP, Division General Manager, STMicroelectronics. The company targets Common Criteria EUCC and EMVCo certifications for the ST54M by July.

ST54M Chip Integrates PQC Hardware with Secure Element Features

STMicroelectronics has created a single-die solution combining PQC acceleration with Near Field Communication, a secure element, and embedded SIM functionality, streamlining device design and potentially lowering manufacturing costs. Unlike software-based PQC implementations, the dedicated hardware promises a substantial performance advantage for computationally intensive cryptographic tasks, crucial as quantum computing threats become more significant. The chip’s design addresses the growing need for robust security in increasingly connected mobile devices, supporting applications ranging from contactless payments and transit ticketing to digital identity and automotive access. STMicroelectronics anticipates that these devices will increasingly serve as trusted platforms for sensitive transactions and data, necessitating a proactive approach to future-proof security. A key feature of the ST54M is its hardware acceleration for post-quantum cryptography algorithms, specifically ML-KEM and ML-DSA, facilitating a transition from current hybrid cryptographic approaches toward full post-quantum deployment.

This hardware engine is also designed to defend against sophisticated attacks, including side-channel and fault-injection attempts, building on ST’s existing commitment to secure software libraries like NesLib-PQML and X-CUBE-PQC within its STM32 microcontroller family. Demonstrating a commitment to industry standards, STMicroelectronics is targeting Common Criteria EUCC and EMVCo certifications by July, validating the chip’s suitability for high-security mobile applications and payment systems. Beyond security, the ST54M boasts enhanced RF performance and increased memory capacity, supporting demanding use cases like mobile Point-of-Sale systems and wireless charging, potentially enabling smaller antenna designs and more stable wireless communication. Samples are currently available to customers, with full production and certification slated for completion next month.
