Data Encryption Transmission and Authentication Scheme Based on Blockchain Technology

Abstract

Aiming at the security problem of data network transmission between smart car and server, based on the identity authentication technology in blockchain, a data encryption transmission and authentication scheme is proposed. Based on the identity authentication technology in the blockchain, the identity authentication of the car after data transmission is realized. Through the Diffie-Hellman algorithm, the key exchange between the car and the server is realized. After combining the two technologies, the proposed scheme can not only realize the encrypted transmission of data, but also effectively carry out identity authentication, which greatly improves the security of data transmission between the car and the server.
