Worked on the rdkcentral/meta-rdk-video repository to enhance cryptographic storage reliability within embedded video systems. Developed a Persistent Cryptographic Storage Interface, enabling persistent storage and retrieval of cryptographic objects, and refactored the Vault class to ensure secure acquisition and release of the security processor handle. This approach improved the robustness and lifecycle management of cryptographic operations across the video pipeline. The work was implemented using C and C++, leveraging expertise in cryptography and embedded systems. By focusing on patch management and secure storage, the changes addressed reliability concerns and strengthened the security posture of cryptographic workflows in the video stack.
