Cette publication existe aussi en Français
Infineon Technologies and Thistle Technologies are joining forces to bring stronger protection to Secure Edge AI applications. By integrating Infineon’s OPTIGA™ Trust M into the Thistle Security Platform for Devices, the companies aim to safeguard AI models and the sensitive data they rely on with hardware-backed cryptography.
For eeNews Europe readers, this move highlights a new way to safeguard intellectual property in AI applications and secure training datasets in embedded devices—a challenge increasingly faced by OEMs deploying machine learning at the edge.
Hardware-anchored protection for AI
Thistle’s updated Security Platform for Devices integrates Infineon’s OPTIGA™ Trust M as a hardware-based root of trust. This combination provides ready-made, cloud-managed security components for Linux-based systems and microcontroller-driven products. Instead of building custom stacks, OEMs can deploy proven security foundations within hours and scale them across fleets.
The OPTIGA™ Trust M security controller enables tamper-resistant key storage, secured provisioning, and cryptographic operations such as encryption and decryption. Devices authenticate and deploy only trusted AI models.

Key features of the Secure Edge AI solution include:
- Hardware-backed model encryption: Each device stores a unique AES 256-bit key in OPTIGA™ Trust M. This keeps model encryption keys inside the secure element. Even disassembled or decommissioned devices cannot expose manufacturer IP.
- Secured model provenance: Over-the-air updates are cryptographically signed and traceable back to the training platform, offering tamper-evident delivery.
- Signed data and lineage: Devices can sign collected data and tag it with provenance metadata. Downstream systems can then verify both the data integrity and the model version.
Industry voices and availability
“At Infineon, we are pleased to expand our collaboration with Thistle Technologies to deliver stronger protection for AI models running at the edge,” said Animesh Ranjan, Head of Partnerships & Ecosystem at Infineon. “By combining the OPTIGA Trust M security solution with the Thistle Security Platform, we enable device makers to safeguard their AI with hardware-anchored security that is both practical and scalable.”
Window Snyder, CEO of Thistle Technologies, added: “It is always our goal to make robust security capabilities accessible for device makers. With Infineon’s OPTIGA Trust M and the Thistle Security Platform, manufacturers can protect AI models and data with proven cryptography and deploy at scale quickly. Together we give customers a straightforward way to ship devices that can securely verify, encrypt, and update AI models.”
The Secure Edge AI solution is available now as part of the Thistle Security Platform.
