Abstract
Modern autonomous vehicles are getting progressively popular and
increasingly getting closer to the core of future development in transportation
field. However, there is no reliable authentication mechanism for the unmanned
vehicle communication system, this phenomenon draws attention about the
security of autonomous vehicles of people in all aspects. Physical Unclonable
Function (PUF) circuits is light-weight, and it can product unique and
unpredictable digital signature utilizing the manufacturing variations occur in
each die and these exact silicon features cannot be recreated theoretically.
Considering security issues of communication between Electronic Control Units
(ECUs) in vehicles, we propose a novel delay-based PUF circuit using all the
available logical components in every two-slice within Configurable Logic
Blocks (CLBs) in Field Programmable Gate Array (FPGA) chips, which is
significantly suitable for circuit authentication in ECUs of autonomous vehicles
and is a significant improvement over the usual arbiter PUF in resource
occupation in FPGA chips, that is to say it can get stronger resistance to security
risks with less logic resource overhead. Our PUF design is resource efficient so
that it can exactly be applied to the source-constrained devices such as in-vehicle
ECUs. It effectively reduce the risk of the messages delivered between ECUs
being tampered and then vehicle be illegally controlled by adversary. We
simulated the proposed PUF circuit in simulator and implemented it on Xilinx
boards under different conditions to obtain experimental results, the analyzed
result proves that the proposed PUF satisfies the properties of Uniqueness and
Stability. Finally, the ECUs authentication mechanism utilizing our PUF circuit
is introduced.
