Worked on enhancing host attestation within the google/go-tpm-tools repository, focusing on improving the accuracy, efficiency, security, and integrity of the attestation process. The engineering approach involved correcting NV counter attributes, removing redundant fields from the dummy host attestation, and updating the PCR index to include CPU hardware ID measurement, thereby aligning with hardware-backed identity verification requirements. Utilized Go for backend development, applying security best practices and precise measurement points to strengthen the attestation workflow. The work demonstrated attention to code quality and maintainability, addressing both functional improvements and technical debt within the TPM-based attestation codebase over the month.
