Query: Secure Vehicle Communications Using Proof-of-Nonce Blockchain   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.
