# meta-essa-mx8mm

BG Network's Embedded Security Software Architecture (ESSA), a collection of scripts, recipes, configurations, and documentation for Linux, enhances cybersecurity for IoT devices, including secure boot, encryption and/or authentication. The ESSA enables engineers to extend a hardware root of trust to secure U-Boot, the Linux kernel, and applications in the root file system.

To provide strong cybersecurity without compromising performance or functionality, this architecture leverages:

  • In-silicon cryptographic accelerators and secure memory
  • Linux security features

The ESSA is Linux based and when used in conjunction with the SAT will support:

  • Hardware root of trust extended to the rootfs and software application layer Configuration of Linux Device Mapper (DM) cryptographic functions.
  • Use of AES-XTS and HMAC-SHA256 cryptographic algorithms.
  • Root of trust extended to Linux userspace.

Supported board

The following board is the only board tested in this release.

Quick Start Guide

See the Quick Start Guide for instructions of building core image and for a quick demo of DM-Crypt with CAAM's black key.
