[Abstract]:With the development of economy, the number of motor vehicles is increasing and the road construction is becoming more and more complicated, which is accompanied by a large number of traffic data. In the face of a large number of traffic data from different data sources and different data platforms, it is difficult for the traditional traffic business processing platform to meet the increasing demand of the system. The sensitive information in the traffic system, such as the signal light control information and the electronic display control information, affects the traffic safety all the time, and its data safety also needs to be paid enough attention. In view of the complexity of traffic system business logic, the diversity of data sources and data platforms, this paper uses Java Web and database technologies to realize intelligent transportation system based on BES architecture. According to the application scenario and the idea of modular design, the system docks various data sources in the system, stores the data from different data sources uniformly, and provides a consistent data operation interface for the application layer. Aiming at the common cross-platform business, the platform fusion layer is used to realize the interaction of various data platforms, encapsulate the platform operation, provide a unified interface, adapt the call flow of the application layer, and then realize the simplification and unification of the cross-platform business. For the transmission of sensitive data such as control information and content information in intelligent transportation system, this paper analyzes the data structure of sensitive information and the requirement of response efficiency, and classifies and processes the sensitive information. A broadcast authentication scheme based on intelligent transportation system is proposed and implemented. The scheme uses RSA digital signature technology and Rapid Authentication broadcast authentication protocol for reference and realizes the broadcast authentication scheme based on intelligent transportation system. On the basis of both data processing efficiency and data security, the scheme realizes the broadcast authentication scheme based on intelligent transportation system. Ensure the integrity of the transmission of sensitive information, authenticity, etc. Through performance test and security analysis, the proposed scheme has high computational efficiency and can resist tampering, replaying and forgery attacks.
