Existing IoT protocols cannot be directly applied to big data collection scenarios, and the complexity of conventional dynamic network structures and vehicle nodes will increase as the amount of data increases, and safety requirements become higher and higher.Aiming at the security guarantee of vehicle data resource transmission, this paper proposes a new big data collection security mechanism.After the vehicle information is connected to the network through the big data registration center, the information is combined, and the big data center algorithm is implemented by "identification" and "single sign-on".A new secure big data collection scheme is proposed, processing large-scale vehicle data structure and aggregation node data, performing a second login and then to data security collection and storage to complete the safety performance evaluation.The research results show that the new data security exchange algorithm reduces the message digest and random key overhead, increases the efficiency of big data in the Internet of Vehicles by 21.67%, and increases the vehicle node mode by 26.41%.
