Infineon’s OPTIGA for more secure AI and ML models
31 October 2025
AI & ML
Infineon Technologies provides its OPTIGA Trust M security solution to Thistle Technologies for its new cryptographic protection for on-device AI models to its security software platform for embedded computing products based on the Linux operating system or on a microcontroller. The new capabilities in the Thistle Security Platform for Devices, along with Infineon OPTIGA Trust M security solution as tamper-resistant hardware-based root-of-trust, protect the valuable intellectual property in the AI models deployed in edge AI applications, and in the training data sets on which they are based.
The Thistle Security Platform for Devices that includes the Infineon OPTIGA Trust M security solution, provides ready-made, cloud-managed security components which integrate seamlessly into Linux OS-based devices and microcontrollers. Instead of building and maintaining a one-off cybersecurity stack, OEMs can deploy a proven, continuously updated foundation in hours, and scale it across large, heterogeneous fleets of devices.
The Security Platform enables both secured boot and over-the-air (OTA) updating, and is compatible with a broad range of microprocessors, systems-on-chip (SoCs) and microcontrollers. Infineon OPTIGA Trust M security controller enables secured key provisioning, tamper-resistant key storage, and efficient cryptographic operations for encryption and decryption for taking care that only trusted, authenticated, and verified AI models are deployed in edge AI applications.
