Abstract : Security in embedded systems remains a major concern. Untrustworthy authorities use a wide range of software attacks. This demo introduces ARMHEx, a practical solution targeting DIFT Dynamic Information Flow Tracking implementations on ARM-based SoCs. DIFT is a solution that consists in tracking the dissemination of data inside the system and allows to enforce some security properties. In this demo, we show an implementation of ARMHEx on Xilinx Zynq SoC. Especially, we show how the required information for DIFT is recovered with the help of traces produced by CoreSight components, static analysis and instrumentation.

Keywords : DIFT CoreSight ARM Debug components Information Flow tracking Zynq SoC Zynq SoC IFT Dynamic information flow tracking
