Arm Mbed OS is a platform operating system designed for the internet of things
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:23 commits, 4 PRs, 32 comments in 14 days
Contributions summary:Mohammad primarily focused on integrating and extending the Arm Mbed OS, a platform operating system designed for IoT devices, with a specific focus on the PSA (Platform Security Architecture) security features. Their contributions involved adding entropy injection capabilities to the Secure Partition Manager (SPM) and integrating PSA crypto services. These changes included modifications to various source files related to cryptographic services, PSA setup, and entropy handling, indicating a strong focus on secure firmware development within the Mbed OS ecosystem. Furthermore, tests were added to validate the implemented PSA entropy injection feature.
