Fortifying Energy Automation with Scalable, Compliant Security
When a leading energy automation provider faced the challenge of safeguarding critical systems and meeting stringent compliance requirements, Lynx delivered. With VigiShield, the client achieved secure boot, PKCS11-based key management, and reliable update mechanisms that future-proof their systems while meeting tight timelines.

Challenge
Solutions Rooted in Proven Security Principles
From Buildroot to Yocto: Scalable Platforms for Tomorrow's Needs
Transitioning from a Buildroot environment to Yocto unlocked scalability and maintainability for the client’s i.MX7 and i.MX6 platforms. By unifying their systems, Lynx provided a consistent, secure foundation across product lines—streamlining updates, reducing complexity, and enabling long-term compliance.
Secure Boot: A Strong Chain of Trust
Using VigiShield, Lynx implemented secure boot with cryptographic keys stored in on-chip fuses. This ensured software authentication and a robust chain of trust from the bootloader to the root filesystem, protecting against unauthorized access.
Reliable Updates with A/B Partitioning
Unreliable updates can lead to costly downtime. Lynx solved this with a secure A/B partitioning system, incorporating a fallback mechanism that allows recovery in case of failures. For the client, this meant confidence in every deployment.
