Implementation in Hardware

Most hardware teams struggle with secure boot implementation - from choosing the right root of trust to configuring boot chains correctly. A single misconfigured fuse can brick expensive prototypes.

We guide organizations from initial architecture through production deployment, having implemented secure boot across multiple silicon vendors.

Once your foundation is solid, bitSign provides the signing infrastructure to keep it secure in production.

Linux Driver

Accessing hardware keys from higher-level software is crucial for bootloader verification and system recovery. Our upstream contributions mean reduced long-term maintenance - no custom driver patches to maintain as kernels evolve.

nvme: add new NXP QorIQ eFuse driver

Add SFP (Security Fuse Processor) read support for NXP (Freescale) QorIQ series SOC's.

This patch adds support for the T1023 SOC using the SFP offset from the existing T1023 device tree. In theory this should also work for T1024, T1014, and T1013 which uses the same SFP base offset.
