March 2026: Delivered targeted platform configuration for PSA TLS sample on NRF54LS05DK within nrfconnect/sdk-nrf, enabling builds and comprehensive testing on the 54ls hardware. This work extends hardware compatibility, accelerates security testing, and improves verification coverage, reducing integration risk and enabling faster validation cycles for PSA TLS on Nordic platforms.

February 2026 focused on hardening hardware enablement for LS05B variants in the nrfconnect/sdk-nrf repository. Key work targeted reliability and security by preventing enabling KMU hardware that is not present on LS05B devices. This was achieved through a Kconfig change that disables KMU HW configuration for LS05B, ensuring the system does not activate non-present hardware during boot. Commit referenced: 1e1f22f9518e79d690db38565e3cd9e33a0b0d66 (nrf_security: KMU HW config LS05B); Signed-off-by: Paul Fleury <paul.fleury@nordicsemi.no>. Impact: improves runtime stability, reduces risk of boot-time failures, and enhances security posture for LS05B deployments. The change is isolated, well-traced, and aligns with established code hygiene practices in sdk-nrf.

Delivered PSA TLS sample secp384r1 certificate support in the nrfconnect/sdk-nrf repository for April 2025. This feature enables use of the secp384r1 certificate curve in the PSA TLS sample, with build-time configurability and expanded test coverage. Changes include a build configuration update to conditionally include new certificate files, addition of secp384r1 certificate files, and sample.yaml updates to cover secp384r1 test scenarios.

In 2025-01, delivered expanded TLS 1.3 test coverage for the PSA crypto samples in the nrfconnect/sdk-nrf repository, adding new TLS 1.3 configurations and server/client test cases that exercise the ECDSA with the cracen security backend. Also fixed TLS 1.3 test suite directory naming to consistently reflect the TLS version, improving test discovery and maintainability. These changes reduce risk by strengthening security validation and streamline CI/testing workflows for TLS-related changes.

December 2024: Delivered a targeted library upgrade in NordicBuilder/sdk-nrf, upgrading the Oberon PSA Crypto Library to a newer version as specified in west.yml to enable crypto testing. The change broadens test coverage for embedded cryptography on the NRF platform while preserving build stability. No major bugs were reported this month; all changes underwent validation through existing test pipelines and documentation for maintainability.

Monthly work summary for 2024-11 focusing on key accomplishments in NordicBuilder/sdk-nrf. Delivered TLS 1.3 support in PSA crypto samples and upgraded the Oberon PSA Crypto library dependency, enhancing security, interoperability, and maintainability.
