Don't Make These Mistakes When Bringing Secure Boot to Production

Enabling Secure Boot on an NVIDIA Jetson is often the first milestone toward securing an embedded product. NVIDIA provides excellent documentation explaining how to generate signing keys, and fuse devices, making it possible to establish a trusted boot chain.

However, enabling Secure Boot is only the beginning.

One of the most common mistakes teams make is assuming that the same process used during development can also be used in production. While this may work for early prototypes, it quickly becomes a security and operational challenge as products scale.

Production environments introduce questions that are rarely answered by traditional Secure Boot documentation:

• Where should production signing keys be stored?

• How can CI/CD pipelines generate signed images without exposing private keys?

• How can manufacturing securely sign or flash production devices?

• Who should have access to signing operations?

• How can signing activities be audited and managed across multiple teams?

  
  

If these challenges are not addressed early, organizations risk exposing sensitive signing keys, relying on manual signing processes, creating unclear operational responsibilities, and ultimately weakening the security of every device deployed in the field.

Secure Boot is therefore much more than enabling authenticated device. It requires a secure infrastructure capable of protecting signing keys, automating signing operations, and integrating securely with development, CI/CD, and manufacturing floor.

Development vs. Production

The workflow used during development is fundamentally different from the one required for production:

During development, it is common for engineers to generate keys locally and execute signing operations directly from their computers. This approach is simple and effective for prototyping but does not scale to commercial products.

In production, signing operations should be isolated behind a dedicated signing service. Private keys remain protected inside a secure environment (ideally backed by an HSM) while developers, CI/CD pipelines, and manufacturing systems submit signing requests through controlled interfaces. This approach improves security, simplifies auditing, and reduces the risk of exposing production credentials.

How RidgeRun Can Help

Building a production-ready Secure Boot infrastructure for the first time can be challenging. Designing the signing architecture, integrating build systems, protecting production keys, and automating the process all require careful planning.

To help engineering teams accelerate this process, we've created a series of practical guides covering each major challenges of a production signing infrastructure:

Guide	Description
Setting Up Your Signing Server	Deploy a dedicated signing service that securely manages signing requests while protecting production keys.
Integrating Your Signing Server with Yocto	Configure Yocto to automatically submit signing requests as part of the image build process.
Integrating Your Signing Server with CI/CD	Get practical tips on access roles and secure boot production infrastructure needed.
Integrating NVIDIA Flashing Scripts with an HSM	Protect production keys using hardware-backed security while maintaining compatibility with NVIDIA's flashing tools.

Together, these guides provide a practical roadmap for designing a secure, scalable signing infrastructure for NVIDIA Jetson-based products.

Ready to Bring Your Product to Production?

Every product has unique security requirements and manufacturing constraints. At RidgeRun, we help engineering teams design and integrate production-ready Secure Boot infrastructures tailored to their products, from signing servers and HSM integration to Yocto and CI/CD automation.
