Towards a hardware-assisted information flow tracking ecosystem for ARM processors
This work addresses the need for more efficient and portable information flow tracking in hardware security, though it appears incremental by building on existing debug features.
The paper tackled the problem of inefficient information flow tracking on ARM processors by developing a hardware-assisted approach using ARMv7 debug components, achieving initial results on silicon area and time overheads.
This work details a hardware-assisted approach for information flow tracking implemented on reconfigurable chips. Current solutions are either time-consuming or hardly portable (modifications of both sofware/hardware layers). This work takes benefits from debug components included in ARMv7 processors to retrieve details on instructions committed by the CPU. First results in terms of silicon area and time overheads are also given.
