Crypto trust point (cTp) for secure data sharing among intelligent vehicles

Tremendous amount of research is going on in the field of Intelligent vehicles (IVs)in industries and academics. Although, IV supports a better convenience for the society, but it also suffers from some concerns. Security is the major concern in Intelligent vehicle technology, due to its high exposure to data and information communication. The environment of the IV communication has many security vulnerabilities, which cannot be solved by Traditional Security approaches due to their fixed capabilities. Among security, trust, data accuracy and reliability of communication data in the communication channel are the other issues in IV communication. Blockchain is a peer-to-peer, distributed and decentralized technology which is used by the digital currency Bit-coin, to build trust and reliability and it has capability and is feasible to use Blockchain in IV Communication. In this paper, we propose, Blockchain based crypto Trust point (cTp) mechanism for IV communication. Using cTp in the IVs communication environment can provide IV data security and reliability. cTp mechanism accounts for the legitimate and illegitimate vehicles behavior, and rewarding thereby building trust among the vehicles. We also propose a reward based system using cTp (exchange of some cTp among IVs, during successful communication). We use blockchain technology in the Intelligent Transportation System (ITS) for the data management of the cTp. Using ITS, cTp details of every vehicle can be accessed ubiquitously by IVs. We evaluation, our proposal using the intersection use case scenario for intelligent vehicles communication.
