Microchip introduces a new real-time platform trust root to provide a complete trust chain for the system platform

     With the change of market demand for security, the platform must also keep pace with the times to defend against network attacks during startup, real-time phase and system update. Faced with new market threats, designers need to assume that the terminals they use are untrustworthy and must find new technologies to protect the system. Microchip Technology Inc announced the launch of CEC1736 Trust Shield series products based on a fully configurable microcontroller. It uses runtime firmware protection beyond the NIST 800-193 Platform Firmware Elasticity Guide to address the above challenges and ensure a safe startup process while establishing a complete trust chain for the system platform.

     CEC1736 solution enriches Microchip's product portfolio to ensure network flexibility of terminal equipment. It has a fully configurable real-time platform trust root, and can implement runtime firmware protection in SPI flash memory and I2C/SMBus filtering to prevent runtime attacks. The authentication function provides reliable evidence to ensure the authenticity of key equipment in the platform. The lifecycle management and ownership transfer functions protect the confidentiality during the entire terminal product lifecycle and product ownership transfer process, so that different operators can safely use the system platform without disclosing information.

     Ian Harris, Vice President of Microchip Computing Products Business Department, said: "Assuming that trusted devices are no longer accepted, unauthorized firmware components must be anticipated and prevented, and peripheral components must not be trusted until trusted. Our CEC1736 Trust Shield series products provide a complete solution to these challenges, simplify the development and configuration of keys and other secrets, speed up time to market, and provide flexibility ahead of threats."

     The advanced hardware cipher suite of CEC1736 Trust Shield series products is equipped with AES-256, SHA-512, RSA-4096, ECC with key size up to 571 bits, and elliptic curve digital signature algorithm (ECDSA) with key length of 384 bits. 384 bit hardware physical non cloning function (PUF) realizes unique root key, symmetric secret, private key generation and protection. This advanced root of trust and security solution complies with NIST 800-193 and OCP security guidelines, allowing rapid adoption of the latest security achievements and standards.

     Microchip's CEC1736 Trust Shield series products cover chips, software, tools, development boards and configuration functions, which can provide customers with the required end-to-end platform firmware protection.

     Fr é d é ric Thomas, Chief Technology Officer of Kudelski IoT, a leading Internet of Things security company, said: "Security is related to business continuity, consumer privacy and national security, and ensuring security is everyone's responsibility. By working with us to independently evaluate their hardware in our advanced security laboratory, Microchip has taken important measures to ensure that CEC1736 Trust Shield products can withstand advanced attacks. This can reassure Microchip customers because they use a safe and advanced microcontroller, which is conducive to the Internet The overall security of the world. "
