Secure Vehicle Communications Using Proof-of-Nonce Blockchain
This addresses security for autonomous driving systems, but it appears incremental as it builds on existing blockchain and physical layer security concepts.
The paper tackles secure vehicle communications by proposing a Proof-of-Nonce blockchain algorithm to ensure physical layer security, achieving safety against quantum computing hackers by generating blocks only when secrecy capacity meets a reference value.
This paper presents an autonomous driving that achieves physical layer security. Proposed vehicle communication is implemented based on Proof-of-Nonce (PoN) blockchain algorithm. PoN blockchain algorithm is a consensus algorithm that can be implemented in light weight. We propose a more secure vehicle communication scheme while achieving physical layer security by defecting PoN algorithm and secrecy capacity. By generating a block only when secrecy capacity is greater than or equal to the reference value, traffic information can be provided only to vehicles with physical layer security. This vehicle communication scheme can secure sufficient safety even from hackers based on quantum computing.
