Data Transmission Security Technology Of Automotive Industry Chain Collaborative Commerce Platform

The automotive industry chain collaborative commerce platform provides a public service platform solution based on the SaaS(Software-as-a-Service) model for Inter-enterprise business collaboration, It is an abstract of a variety of industrial chain of inter-enterprise business systems at a higher level, and it’s goal is to provide a underlying platform supporting rapid development and customization for industrial chain of inter-enterprise business collaboration. As the data transit center of inter-enterprise business collaboration, platform data exchange system is a key component of business collaboration. The data exchange system of automotive industry chain collaborative commerce platform has achieved dynamic data exchange between the platform and the factory system based on Web Service technology currently.As a public service platform running on the Internet, data transmission security is very important, but there are problems such as outside exposure of Web Services interfaces, unencrypted transmission of the SOAP message, and low efficiency of data exchange to be solved in platform data exchange program. How to achieve effective access control, verify the service requester identity, ensure the security of data during transmission, ensure the performance of data exchange system, enhance exchange efficiency and other series of problems should be solved.The features of platform for data exchange is analyzed in depth, all kinds of safety and performance risks are taken into consideration, data security exchange model for the automotive industry chain collaborative commerce platform is proposed in order to meet frequent data exchange of collaborative business platform for the automotive industry chain and high requirements of security during the data transmission. Data security exchange model facing the automotive industry chain collaborative commerce platform is presented in this thesis on the basis of existing data exchange system based on Web Service and data exchange adapter. Overall design and implementation of the model is achieved by studying authentication based on encryption lock, data transmission security based on SOAP extension, data exchange technology and compression technology based on Web Service. Safety problems in the data transfer process are solved in the security solution, and it has been validated in the test under the simulated Internet operating environment.
