Ultra-Lightweight Mutual Authentication in the Vehicle Based on Smart Contract Blockchain: Case of MITM Attack

Abstract

For quite a long time, purchasers have come to depend on the convenience and security and included security that a passive vehicle immobilizer framework offers. These frameworks comprise of a Passive Entry Passive Start (PEPS) innovation, conveyed by the driver, and a Smart Key Unit (SKU), mounted in the vehicle with regards to the principal parts of these frameworks. This paper for the first time shows the cyber vulnerability of PEPS in the vehicle against the man-in-the middle attack (MITM). It enables the hacker to open and begin the vehicle, although there was still a distance between the vehicle and the key. To stop this physical cyber attack, we propose a hearty ultra-lightweight common confirmation technique dependent on the radio frequency identification (RFID) convention that cooperates with a decentralized database to verify the PEPS. A secure blockchain based on smart contract is also developed which is compatible with the mutual authentication in the vehicle. A detailed security analysis is performed on an undefined vehicle to prove the high security of the proposed communication approach when facing MITM.
