Summary
🤩
Rockstar🎓
Top SchoolTamás Bán is a Principal Embedded Software Engineer based in Budapest with nine years focused on secure boot, device attestation and embedded security at Arm. He has driven measurable enhancements to Trusted Firmware-A—adding secure-enclave backends, new measurement APIs, an MHU driver and RSS integration—and contributed hardening and RAM-load upgrade work to the widely used mcuboot bootloader. Prior to his current role he built deep low-level expertise at Ericsson in packet-based synchronization (IEEE1588), kernel drivers and distributed Ethernet/IP systems. Tamás blends hands-on C and embedded systems work with CI/test improvements and cross-OS mitigation strategies (Zephyr, Mynewt, TF-M), making him effective at turning security requirements into testable firmware. His academic background in semiconductor design complements a pragmatic approach to system-level threats and fault-injection countermeasures. Colleagues rely on him for complex secure-boot architecture and for bridging hardware constraints with robust software defenses.

Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:101 reviews, 11 commits, 16 PRs in 3 years 6 months
Contributions summary:Tamás primarily contributes to the secure boot process for microcontrollers, focusing on features like RAM-load upgrade modes and fault injection mitigation techniques. Their work includes modifying bootloader code to support loading and executing images from RAM, enhancing security against fault injection attacks by introducing software countermeasures in multiple system levels (Zephyr, Cypress, Mynewt and bootutil). They also improve build processes for testing with TF-M, updating the CI/CD configuration and adjusting test suites to include the hardening functionalities.

Read-only mirror of Trusted Firmware-A
Role in this project:Back-end Developer / Embedded Systems Engineer
Back-end Developer / Embedded Systems EngineerContributions:22 commits in 10 months
Contributions summary:Tamás primarily focused on enhancing the measured boot and attestation functionality of the Trusted Firmware-A project. Their contributions involved implementing a secure enclave backend for storing measurements, which required adding new APIs for extending measurements, along with integrating the Runtime Security Subsystem (RSS). The user also developed an MHU driver and communication protocol to enable secure communication and delegate attestation. This included adding supporting code to utilize the PSA API and fix communications protocol issues.
