Secure Boot For Embedded Systems - An Overview

Product owners has the requirements to ensure that code being run on their devices are theirs and not from an unintended or malicious source. This can be made possible only with the underlying execution environment is authentic. It can be achieved with a secure bootloader where the very first part of the code executed is validated by in-built hardware aided mechanism for establishing a root of trust. Further parts can be validated by sequence of software cryptographic algorithms continuing with that chain of trust till the device is powered down. Embien specializes in developing Secure Boot for Embedded Systems. Having worked with leading semiconductor companies, in some cases, helping them with developing secure bootloaders, we have unparalleled expertise in implementing them on various architectures. We understand the nuances and challenges in managing performance, processor/memory resources and come up with best possible solutions for all your secure boot requirements.

First Line of Defence for Embedded Security

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.
