The NSA is pushing for post-quantum readiness in the computer and data center industry within the next two years. Microchip Technology has developed its MEC175xB embedded controllers with embedded immutable post-quantum cryptography technology to assist system architects in meeting changing security requirements.
The National Security Agency (NSA) unveiled the Commercial National Security Algorithm Suite 2.0 (CNSA 2.0) to provide a collection of quantum-resistant cryptographic standards in response to advances in cryptography research and the need for more robust security measures.
The MEC175xB family, a standalone controller, uses a modular design to let developers effectively implement post-quantum cryptography, assisting in ensuring long-term data protection without sacrificing current functionality.
These low-power controllers are built using an advanced Enhanced Serial Peripheral Interface (eSPI), adjustable secure boot solutions, and post-quantum cryptography algorithms recognized by the National Institute of Standards and Technology (NIST).
MEC175xB Controllers Incorporate:
- CNSA 2.0-compliant Module-Lattice-Based Digital Signature Algorithms (ML-DSA),
- Merkle stateful hash-based Leighton-Micali Signature (LMS) verification and Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM) standardized by NIST.
- These new algorithms with quantum attack resistance are implemented in immutable hardware to block attack paths possible on software implementations.
The Controllers Feature:
- Secure boot and secure firmware update schemes configurable to use either CNSA 1.0 or 2.0 or hybrid-based signature verification.
- Attestation capabilities use ML-DSA for signing and key generation to enhance system integrity and authenticity.
- At the core is an Arm® Cortex®-M4F processor with a Memory Protection Unit (MPU) running at 96 MHz to deliver high performance for complex computations and real-time applications.
- The controllers include 480 KB of SRAM, I3C® host and client interfaces and an optional USB 2.0 Full-Speed interface for versatile connectivity.
Development Tools
MEC175xB controllers are compatible with MPLAB® X Integrated Development Environment (IDE), and supported by example projects, such as blinking LEDs, available in the Secure Document Extranet (SDE) and external tools such as Zephyr®. The controllers are also supported by the MEC1753-240 MECC (EV48H83A) development board.
Pricing and Availability
MEC175xB controllers are currently available as part of Microchip’s early adopter program. For additional information, contact a Microchip sales representative, authorized worldwide distributor or visit Microchip’s Purchasing and Client Services website, www.microchipdirect.com.
