A Chip That Prepares Phones for Quantum Threats

A mobile chip combines NFC, eSIM, and security features for payments, digital ID, car keys, and protection against future cyber threats.

STMicroelectronics unveils world’s first ST54M secure mobile chip with post-quantum cryptography for next-generation connected services

STMicroelectronics has introduced the ST54M, a secure mobile chip that combines NFC, secure element, eSIM, and post-quantum cryptography (PQC) support on a single die. The chip is designed to help smartphone and personal electronics manufacturers prepare for future security requirements expected around 2030.

The ST54M includes a hardware accelerator for post-quantum cryptography, allowing device makers to implement security methods designed to protect against future quantum computing threats. By integrating multiple security and connectivity functions into one chip, it also helps reduce component count while supporting secure mobile services.

The chip supports applications such as contactless payments, public transport ticketing, access control, digital identity, mobile connectivity services, digital driving licences, and digital car keys.

As smartphones are increasingly used for payments, identity verification, secure access, and operator services, manufacturers need chips that can handle multiple functions while maintaining security and performance. The ST54M is designed to meet these requirements on a single platform and support the industry’s shift towards post-quantum security.

The device can be used in products developed for mobile network operators, banks, government services, transport systems, automotive applications, digital wallets, and other connected services. It enables manufacturers to introduce stronger security features without changing the existing user experience.

“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. “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.”
