Abstract

The ability to update firmware in embedded systems allows end-users to patch device vulnerabilities and improve functionality. However, this process is often exploited by adversaries in order to inject malicious firmware code into embedded devices. In this paper, we present a framework which enables highly secure and fast firmware update delivery with minimal downtime on embedded devices. The proposed framework utilizes device intrinsic physical characteristics to authenticate firmware packages along with integrated cryptographic modules to ensure the firmware confidentiality and integrity. A proof-of-concept design is implemented on FPGA, which demonstrates high performance with reasonable overheads, while our analysis shows strong security guarantees.
