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.},
