The USB armory board has been created to support the development of a variety of security applications.

The capability of emulating arbitrary USB devices in combination with the i.MX6UL SoC speed, the security features and the flexible and fully customizable operating environment, makes the USB armory the ideal platform for all kinds of personal security applications.

The transparency of the open and minimal design for the USB armory hardware facilitates auditability and greatly limits the potentiality and scope of supply chain attacks.

The secure boot feature allows users to fuse verification keys that ensure only trusted firmware can be ever executed on a specific USB armory board.

The support for ARM® TrustZone®, in contrast to conventional TPMs, allows developers to engineer custom trusted platform modules by enforcing domain separation, between the "secure" and "normal" worlds, that propagates throughout all SoC components, and therefore not only limited to the CPU core.

An excellent overview of the technology and its support for the i.MX series of SoC can be found at the Genode framework project.
