Microchip Technology (NASDAQ: MCHP) announced the expansion of its Trust Shield portfolio with two new post-quantum cryptography controllers, the TS1800 Platform Root of Trust controller and the TS50x secure boot controller.

The TS1800 functions as an external Platform Root of Trust controller, providing secure boot, firmware updates, attestation and certificate handling using hardware-accelerated post-quantum cryptography. The device implements National Institute of Standards and Technology standardized algorithms including ML-DSA, LMS verification and ML-KEM.

Built around an Arm Cortex-M4F processor operating at up to 192 MHz, the TS1800 delivers twice the processing performance of previous generations of Microchip root of trust controllers. The device includes USB 2.0 connectivity, which reduces firmware update times compared to I²C and Serial Peripheral Interface connections.

The TS50x family provides a post-quantum cryptography secure boot solution for systems that do not require the full Platform Root of Trust feature set. These devices focus on verification operations of both post-quantum cryptography and classic cryptography, such as Elliptic Curve Cryptography P-384, on signatures of firmware booting from SPI Flash.

Both controllers support requirements such as NIST SP 800-193 platform resiliency guidelines and are designed to address cybersecurity mandates including the European Cyber Resilience Act and Commercial National Security Algorithm Suite 2.0.

The devices are available as part of the pre-configured TrustFLEX platform and are currently offered through Microchip's early adopter program. The controllers run on Microchip's fourth-generation Soteria firmware operating on Zephyr RTOS.

The announcement follows industry preparation for the transition to post-quantum cryptography as organizations address emerging security standards across data center, compute, defense, telecommunications and infrastructure applications.
