PROFILE
Rithic Chellaram Hariharan
Rithic contributed to the nxp-upstream/zephyr repository by engineering robust security and connectivity features for embedded systems. He enhanced cloud and IoT device security by implementing new TLS 1.2 and 1.3 ciphersuites in mbedTLS using C, addressing both confidentiality and regulatory requirements. Rithic also resolved a signing algorithm issue to align with best practices for secure communications. In a subsequent update, he developed persistent TLS/DTLS session caching across device reboots, leveraging the Zephyr settings subsystem and Kconfig for backend-agnostic support. His work demonstrated depth in C programming, embedded networking, and security protocols, improving efficiency and reliability for connected devices.

Apr 1, 2026April 2026 monthly summary for nxp-upstream/zephyr: Delivered persistent TLS/DTLS session caching across device reboots, enabling session resumption after power cycles; backend-agnostic via the settings subsystem; integrated into core networking and the http_get sample via an overlay; added configurable session cache prefix; updated documentation and samples to demonstrate usage. Impact: reduces TLS handshake overhead after reboots, lowering CPU and energy use while improving connection reliability for devices with frequent restarts. Technologies demonstrated include TLS/DTLS, session caching, Zephyr settings subsystem, Kconfig exposure, and sample documentation practices.
