LIGHTWEIGHT RECONFIGURATION SECURITY SERVICES FOR AXI-BASED MPSOCS

Nowadays, security is a key constraint in MPSoC develop-ment as many critical and secret information can be stored and manipulated within these systems. Addressing the pro-tection issue in an efficient way is challenging as information can leak from many points. However one strategic compo-nent of a bus-based MPSoC is the communication architec-ture 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 protec-tion of the whole system. Attacks can be detected and dis-carded before system corruption. In this work, we propose a lightweight solution to dynamically update hardware fire-wall 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 imple-mentation demonstrates an area overhead of around 11 % for the adaptive version of the hardware firewall compared to the static one. 1
