Abstract

The PUF-based VANET protocol has been widely studied for its ability to provide additional anti-counterfeiting features to devices. However, most PUF-based VANET protocols only protect the vehicle without considering the risk of copying secrets for the Roadside Unit (RSU), and do not consider the huge computational cost of error correction algorithms on embedded devices. Therefore, in this paper, we design a lightweight multi-PUF-based VANET protocol. In the proposed protocol, PUF is designed to be placed on both the vehicle and RSU to avoid the security threat posed by fake nodes, providing higher security of the system. Combined with the algorithms of reverse fuzzy extractor and fuzzy extractor, the computing resources can be reasonably allocated, and the delay can be reduced to the maximum extent. Experiments show that the proposed protocol has lower computational cost and higher security than the traditional PUF protocol.
