The rise of the Internet of Things (IoT) has dramatically increased the number of low-cost embedded devices. Being introduced into today’s connected cyber-physical world, these devices now become vulnerable, especially if they offer no protection mechanisms. In this work we present a hardware/software co-designed memory protection approach that provides efficient, cheap, and effective isolation of tasks. The security extensions are implemented into a RISC-V-based MCU and a microkernel-based operating system. Our FPGA prototype shows that the hardware extensions use less than 5.5% of its area in terms of LUTs, and 24.7% in terms of FFs. They impose an extra 28% of context switch time, while providing protection of shared on-chip peripherals and authenticated communication via shared memory.
