Microchip Technology has announced a new cryptography-enabled microcontroller (MCU), the CEC1712 MCU with Soteria-G2 custom firmware – designed to stop malicious malware such as rootkit and bootkit for systems that boot from external Serial Peripheral Interface (SPI) flash memory.
Microchip’s Soteria-G2 custom firmware on its full-featured CEC1712 Arm Cortex-M4-based microcontroller provides secure boot with hardware root of trust protection in a pre-boot mode for those operating systems booting from external SPI flash memory. In addition, the CEC1712 provides key revocation and code rollback protection during operating life enabling in-field security updates.
Complying with NIST 800-193 guidelines, the CEC1712 protects, detects and recovers from corruption for total system platform firmware resiliency. The secure boot with hardware root of trust is critical in protecting the system against threats before they can load into the system and only allows the system to boot using software trusted by the manufacturer.
“A particularly insidious form of malware is a rootkit, because it loads before an operating system boots and can hide from ordinary anti-malware software and is notoriously difficult to detect,” said Ian Harris, vice president of Microchip’s computing products group. “One way to defend against root kits is with secure boot. The CEC1712 and Soteria-G2 firmware is designed to protect against threats before they can be loaded.”
The CEC1712 secure bootloader loads, decrypts and authenticates the firmware to run on the CEC1712 from the external SPI flash. The validated CEC1712 code subsequently authenticates the firmware stored in SPI flash for the first application processor. Up to two application processors are supported with two flash components supported for each. Pre-provisioning of customer-specific data is an option provided by Microchip or Arrow Electronics.
“Secure provisioning for some of Microchip`s flagship products is an important part of our offering and the Soteria-G2 firmware and CEC1712 microcontroller are targeted to protect systems,” said Aiden Mitchell, vice president of IoT at Arrow Electronics. “Customers will increasingly seek such offerings as we approach the 5G era and go more into connected solutions and autonomous machines.”
In addition to preventing malicious malware during pre-boot in 5G and data center operating systems, Microchip’s CEC1712 and Soteria-G2 combination is a security enabler for connected autonomous vehicle operating systems, automotive Advanced Driver Assisted Systems (ADAS) and other systems that boot out of external SPI flash.
