In a security standpoint, for a device deployed in the field, the first and foremost requirement is to ensure that the running firmware is genuine. The device must validate its authenticity before start execution to ensure that it is not running a tampered program. In a simple MCU based design, there might be only one integrated firmware whereas in a complex OS based system there will be a sequence of software executed - bootloader, kernel/OS, start-up services and finally user applications. Thus, there is a requirement to establish a chain of trust right from the first instruction executed at the bootloader to the user application.

Embien has been in the forefront of embedded device development for more than a decade and is helping vendors secure their products with various cutting-edge technologies. We ensure that our system software begins from ensuring code validation, confirming authenticity before execution & establishing the root of trust successively. We also make sure that underlying security mechanisms such as High assurance boot (HAB), Trusted Platform Module (TPM), Cryptographic Accelerator and Assurance Module (CAAM), Hardware Cryptographic engines are put to full use in establishing secure hardware Root of Trust.
