Using an unordered list, summarize the following article with between 4 and 8 key points.
The company has introduced the TA101 TrustFLEX secure authentication integrated circuit (IC) and the TA101 TrustMANAGER, which incorporates the keySTREAM cryptographic key‑management service from Kudelski Labs.
The new additions are intended to support products subject to CRA requirements as well as developers working on software‑defined vehicle (SDV) architectures.
The updated platform supports multiple deployment models. Manufacturers with established cloud infrastructure can integrate factory‑preconfigured TrustFLEX ICs to manage cryptographic keys and firmware securely at scale. Those without such infrastructure can use the TrustMANAGER platform for cloud‑based key lifecycle management and firmware‑over‑the‑air (FOTA) updates.
Microchip says this approach gives companies flexibility in how they address increasingly stringent security requirements while reducing implementation burdens.
For industrial environments, the Trust Platform is designed to support compliance with IEC 62443 and the CRA through features such as PKI-based authentication, authenticated communications, centralised security management and secure firmware updates. Microchip also offers in‑factory or in‑field provisioning services to help streamline conformity assessments and technical documentation.
“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 arrives preconfigured for common security functions, enabling hardware‑based authentication without the need for developers to create cryptographic setups from scratch. Microchip says this can reduce development time and documentation requirements, while also lowering security risks compared with manually configured ICs. Key provisioning takes place in Microchip’s certified facilities following Common Criteria processes.
The TA101 TrustMANAGER (TA101‑TMNGTLS) provides remote management of cryptographic keys throughout a product’s lifecycle. Integrated with Kudelski’s keySTREAM SaaS platform, it supports secure in‑field provisioning, monitoring, key revocation, code signing and FOTA updates. In automotive applications, the device is intended to provide scalable, secure software updates and key management to ensure that only authenticated commands and software reach electronic control units (ECUs). This capability supports compliance with ISO/SAE 21434 and UNECE WP.29 cybersecurity regulations.
Together, the TA101‑TFLXTLS and TA101‑TMNGTLS aim to create a continuous hardware‑rooted chain of trust from manufacturing through deployment and onwards into in‑field operation. Microchip positions the devices as tools to help manufacturers accelerate development of compliant products across industrial and automotive sectors.
Both components integrate with the MPLAB X Integrated Development Environment, Microchip’s CryptoAuth PRO development board (EV89U05A) and the CryptoAuthLib software library. The Trust Platform Design Suite (TPDS) offers onboarding support including training, prototyping tools and access to secure provisioning services.
