As cybersecurity regulations become stricter worldwide, product manufacturers are under increasing pressure to integrate security measures early in the design process. Addressing this growing challenge, Microchip Technology has expanded its Trust Platform with the introduction of the TA101 TrustFLEX secure authentication IC and TA101 TrustMANAGER integrated with the keySTREAM® service developed by Kudelski Labs. The enhanced platform aims to help developers comply with emerging regulations such as the EU Cyber Resilience Act while also supporting cybersecurity requirements for industrial systems and modern automotive architectures.
With regulatory frameworks evolving rapidly, organizations must implement robust security strategies that protect products throughout their lifecycle. Therefore, Microchip designed the TA101 Trust Platform to support flexible deployment models that simplify cryptographic key management, firmware updates, and device authentication. In particular, the solution targets developers working on connected industrial equipment and software-defined vehicles, where strong security controls are becoming essential for compliance and operational safety.

The platform provides two distinct implementation approaches depending on the organization’s infrastructure capabilities. Companies that already operate a secure cloud environment capable of managing cryptographic keys and firmware can deploy factory-configured TA101 TrustFLEX secure authentication ICs. These chips come preconfigured for common security use cases, allowing developers to implement hardware-based authentication quickly without building complex cryptographic frameworks from scratch.
On the other hand, organizations without a dedicated cloud infrastructure can rely on the TA101 TrustMANAGER platform. This solution integrates with the keySTREAM Software-as-a-Service platform from Kudelski Labs to deliver cloud-based cryptographic key lifecycle management and firmware-over-the-air (FOTA) update capabilities. As a result, developers gain a streamlined path to implementing secure device provisioning, key monitoring, revocation processes, and authenticated firmware deployment across distributed devices.
For industrial systems, the Trust Platform helps organizations align with cybersecurity frameworks such as IEC 62443 while also supporting compliance with the EU Cyber Resilience Act. It enables PKI-based authentication, secure communications, centralized security control, and authenticated firmware updates. Additionally, Microchip’s factory and field provisioning services assist manufacturers with regulatory conformity assessments and documentation requirements, reducing the operational burden of compliance.
“Security requirements are expanding rapidly, presenting developers with significant challenges in complexity of implementing cryptographic key management and secure updates,” said Nuri Dagdeviren, corporate vice president of Microchip’s secure computing group. “At Microchip, we believe security can facilitate innovation, not slow it down. Our Trust Platform simplifies the security lifecycle and enables easy integration, helping customers bring products to market faster and with confidence.”

The TA101 TrustFLEX (TA101-TFLXTLS) IC is factory-configured for common authentication scenarios, which significantly reduces development complexity and documentation effort. Cryptographic keys are securely provisioned within Microchip’s certified manufacturing facilities following Common Criteria practices. Consequently, developers can focus on product functionality rather than managing complex security configuration processes.
Meanwhile, the TA101 TrustMANAGER (TA101-TMNGTLS) solution enables remote management of cryptographic keys across the entire product lifecycle. Integrated with the keySTREAM SaaS platform, it supports secure in-field provisioning, monitoring, code signing, key revocation, and FOTA updates. In automotive applications, this functionality becomes particularly valuable for software-defined vehicle architectures. The solution ensures that electronic control units accept only authenticated software and commands, helping organizations align with ISO/SAE 21434 cybersecurity guidelines and UNECE WP.29 automotive regulations.
Together, the TA101-TFLXTLS and TA101-TMNGTLS solutions establish a continuous hardware-rooted chain of trust from manufacturing to deployment and ongoing operation. By combining secure hardware, lifecycle key management, and scalable cloud integration, Microchip aims to help manufacturers accelerate compliance-ready product development across industrial and automotive sectors.
To support developers further, the TA101 devices integrate with MPLAB X Integrated Development Environment and are compatible with Microchip’s CryptoAuth PRO development board and CryptoAuthLib software library. In addition, the Trust Platform Design Suite provides onboarding support, training resources, prototyping tools, and secure provisioning access, enabling developers to build and deploy secure products more efficiently.
