Worked on enhancing authentication security within the tianocore/edk2-platforms repository by improving the User Authentication System’s salt generation process. Integrated RngLib and the GetRandomNumber32 function to replace insecure NULL seeds, ensuring cryptographically secure randomness for authentication salts. This update required careful dependency management, making RngLib a mandatory component for the affected module and promoting consistent security standards across builds. Focused on embedded systems and UEFI development using C, the work emphasized reliability and traceability by aligning changes with security best practices. No major bugs were reported, and the groundwork was laid for ongoing improvements in authentication robustness and auditability.
