Crypto Quantique and Attopsemi Unite PUF and I-fuse® OTP technology to Deliver Zero-Overhead Device Enrollment on FinFET Technology

LONDON, UK -- April 27,2026 --  Crypto Quantique, a leader in quantum-driven security for the Internet of Things (IoT), today announced an enhanced collaboration with Attopsemi Technology, a premier provider of One-Time Programmable (OTP) IP. Together, the companies are delivering a highly optimised integration of Crypto Quantique’s latest QDID™ PUF technology with Attopsemi’s I-fuse® OTP at TSMC’s 12nm FinFET process.

This partnership significantly simplifies the adoption of unique hardware root-of-trust for advanced semiconductor devices, making Physical Unclonable Functions (PUFs) practical and scalable for highly constrained IoT, automotive, and edge AI applications.

At the core of this advancement is Crypto Quantique’s new QDID architecture, which introduces a breakthrough reduction in the "helper data" required for error correction. By tightly coupling this architecture with I-fuse® OTP, the integrated solution delivers two critical benefits:

• Minimal Silicon Footprint: By drastically reducing the volume of helper data required, customers can utilise a much smaller OTP storage footprint. This preserves valuable silicon area and reduces overall costs while maintaining a highly compact, side-channel attack resilient PUF.
• Zero-Overhead Integration: The solution securely generates, stores, and manages helper data entirely within the PUF. Because this is completely abstracted from the end user, developers can integrate a robust root-of-trust without having to manage complex provisioning, initialisation, or lifecycle handling.

For customers requiring the convenience of a solution compatible with a digital P/R flow with a smaller footprint, Crypto Quantique also offers a fully digital PUF IP, which requires less than 30K gates including the entropy source and associated error correction for generating an immutable seed. The lightweight implementation of the seed generation IP, comprising of Crypto Quantique’s Digital PUF, error correction and the helper data storage is greatly simplified for the SoC integrator with the integration of the Attopsemi’s I-fuse® OTP.

Attopsemi’s I-fuse® OTP complements Crypto Quantique’s PUF IP with a highly reliable, silicon-proven non-volatile memory solution featuring a patented fuse structure and heat-assisted electromigration programming. Its small footprint, low voltage operation, make it an ideal companion for next-generation secure devices at the TSMC 12nm node.

Together, the technologies enable semiconductor companies to deploy secure device identity and seed generation with unprecedented ease. The combined solution reduces design complexity, shortens time-to-market, and lowers total system cost, while simultaneously increasing security assurance.

Shahram Mossayebi, CEO of Crypto Quantique, said: “This collaboration with Attopsemi demonstrates how far PUF technology has evolved. With our latest QDID architecture, we have dramatically reduced helper data requirements, making PUF integration simpler and more efficient than ever. When combined with Attopsemi’s OTP, this creates a seamless, low-footprint root-of-trust solution that removes barriers for semiconductor designers and accelerates adoption across multiple markets.”

Roger Cheng, CEO of Attopsemi, added: “Our I-fuse® OTP is the crown jewel of OTP technologies with extremely high reliability and low program voltage that can achieve very small size without charge pumps and redundancy. Our partnership with Crypto Quantique highlights the strength of combining best-in-class OTP with cutting-edge PUF innovation. The reduced helper data requirement of QDID allows customers to minimise OTP usage while achieving high levels of security and reliability. This is a significant advancement for developers building secure IoT and automotive systems.”

The joint solution is available for integration in devices manufactured on TSMCs advanced 12nm CMOS process, enabling scalable deployment across a wide range of applications.
