Reconfigurable computing is becoming ubiquitous in the form of consumer-based Internet of\nThings (IoT) devices. Reconfigurable computing architectures have found their place in safety-critical\ninfrastructures such as the automotive industry. As the target architecture evolves, it also needs\nto be updated remotely on the target platform. This process is susceptible to remote hijacking,\nwhere the attacker can maliciously update the reconfigurable hardware target with tainted hardware\nconfiguration. This paper proposes an architecture of establishing Root of Trust at the hardware\nlevel using cryptographic co-processors and Trusted Platform Modules (TPMs) and enable over the\nair updates. The proposed framework implements a secure boot protocol on Xilinx based FPGAs.\nThe project demonstrates the configuration of the bitstream, boot process integration with TPM and\nsecure over-the-air updates for the hardware reconfiguration.
