Infineon partner Thistle Technologies integrates its Verified Boot technology with Infineon’s OPTIGA Trust M for enhanced device security

Infineon Technologies AG announced the integration of its OPTIGA™ Trust M security controller, with tamper-resistant hardware certified to Common Criteria EAL6+, with the Verified Boot technology by Thistle Technologies, a pioneer of advanced security solutions for connected devices. This integration enables designers to easily defend their devices against firmware tampering and protect the software supply chain integrity. The result is an improved end-user security, which is particularly important in industries with high security requirements such as healthcare, automotive and device manufacturing.

Thistle Technologies Verified Boot provides a secured boot process for IoT devices. Enhanced integrity checks cryptographically examine that the device firmware has not been tampered with. The solution supports the needs of a wide range of IoT devices for smart homes, smart cities and smart buildings, among others, enabling easy implementation with minimal development time. By leveraging the robust security features of Infineon’s OPTIGA Trust M, including its hardware-based root-of-trust, the technology offers a high level of protection against unauthorized firmware modifications and sophisticated cyberattacks.

“Since the start of our partnership in January 2023, Thistle has developed a software integration for our OPTIGA Trust M within Linux to extend our hardware capability into the application software domain for Linux-based system architectures,” said Vijayaraghavan Narayanan, Senior Director and Head of Edge Identity & Authentication

at Infineon. “The new solution enables our shared customers to quickly enhance the security of their development.”

“Integrating our Verified Boot technology with Infineon’s OPTIGA Trust M is a significant step forward in making it easy to incorporate sophisticated security capabilities into devices quickly,” said Window Snyder, CEO of Thistle Technologies.


The OPTIGA Trust M security controller is available and can be ordered. More information about the Thistle Technologies Verified Boot for OPTIGA Trust M is available at the Infineon Developer Community and the Thistle Blog space.
