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.

Aiming at the poor stability of traditional communication data encryption methods, a point-to-point encryption method of power system communication data based on block chain technology is studied and designed. According to the principle of asymmetric key encryption, the design method makes use of the decentralization and consensus mechanism of block chain technology to develop the public key distribution scheme. After the public key distribution is completed, the sender and receiver of communication data generate the transfer key and pair the key with the public key to realize the pairing between data points. Xor and modular exponentiation are performed on the communication data content, and prime Numbers are used to fill the content data block. The receiver decrypts the data according to the encryption identifier of the data content, and completes the design of the encryption method of communication data point to ground. Through the comparison with the traditional encryption method, it is proved that the larger the amount of encrypted data is, the more secure the communication data can be, and the stability performance is better than the traditional encryption method.
