Abstract: While Embedded Systems are small hardware systems, much added value is often created through the inclusion of specialized firmware. One specific challenge is the secure distribution and update of application specific software. Using a Trusted Platform Module we implement measured firmware updates on a low resource embedded micro-controller platform. We show that it is feasible to ensure both, confidentiality of the update and authenticity of the device for which the update was intended. Furthermore a Trusted Boot mechanism enforces integrity checks during startup to detect malicious code before it is executed. While recent literature focuses on high-performance micro-controller systems or FPGA platforms, our proof-of-concept only requires an 8-bit low-cost off-the-shelf micro-controller.
