Lightweight reconfiguration security services for AXI-based MPSoCs


Nowadays, security is a key constraint in MPSoC development as many critical and secret information can be stored and manipulated within these systems. Addressing the protection issue in an efficient way is challenging as information can leak from many points. However one strategic component of a bus-based MPSoC is the communication architecture as all information that an attacker could try to extract or modify would be visible on the bus. Thus monitoring and controlling communications allows an efficient protection of the whole system. Attacks can be detected and discarded before system corruption. In this work, we propose a lightweight solution to dynamically update hardware firewall enhancements which secure data exchanges in a bus-based MPSoC. It provides a standalone security solution for AXI-based embedded systems where no user intervention is required for security mechanisms update. An FPGA implementation demonstrates an area overhead of around 11% for the adaptive version of the hardware firewall compared to the static one.
