STMicroelectronics had introduced what it claims is the world’s first secure mobile chip with post quantum cryptography designed for next-generation internet connected devices like smartphones and personal electronics.
Called ST54M, the chip is a single-die device that includes hardware accelerator for post-quantum cryptography (PQC), combined with NFC, secure element and eSIM functionality. The chip could support a range of use cases like:
- Contactless payments
- Transit ticketing
- Access control
- Digital identify
- Driving licenses
- Connectivity services
- Digital car keys
However, ST said it could apply to future applications like financial transactions, identify credentials, operator service and secure access.
The chip can allow users to deliver post-quantum-ready implementations with enough time to meet demanding industry-driven market deployment requirements, which are expected to be mandated about 2030.
“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 and division GM at STMicroelectronics. “By combining a PQC hardware accelerator with NFC, embedded secure element, and embedded SIM capabilities, ST54M gives device makers a secure path to start preparing next-generation mobile experiences.”
The ST54M includes a post-quantum, cryptography algorithms like ML-KEM and ML-DSA that support the transition from hybrid cryptographic approaches to full post-quantum deployment, ST said. The hardware engine is designed for emerging PQC requirements while helping protect against side-channel and fault-injection attacks, the company added.
Additionally, the chip integrates large memory capacity to support multiple applications and includes an enhanced RF front end. This can help improve performance with smaller antennas and single-ended configurations, support more stable reader-writer operation and enable point-of-sale and wireless charging use cases.
