Abstract:

Aiming at the current problem that the authentication protocols for vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication in V2X have high computational overheads and are vulnerable to attacks by attackers impersonating legitimate identities, a secure authentication protocol for V2X communication based on the Map-Index physical unclonable function (MI-PUF) is proposed. By introducing PUF to reduce the computational and communication costs of vehicles with its lightweight computing characteristics, the protocol solves the problem of identity impersonation attack with the help of PUF’s unclonable characteristics, and effectively solves the problem of machine learning attack by constructing a key-map and a hash function to process the output signal of PUF. The security under the Dolve-Yao model is verified using the formal verification tool AVISPA, and the protocol can provide basic security for V2I and V2V communication.

Key words: physical unclonable function(PUF), V2X, mutual authentication, MI-PUF, V2X communication security
