ABSTRACT

While data is considered as new production factors in various scenes of the automotive industry. The data interaction of vehicles also raises a significant amount of data security risks and issues. The vehicle development process needs to be considerate of satisfying data security requirements. The main objective of this paper is to investigate a method for decomposing vehicle data security requirements so that they can be met at different levels of the system during development. A principle of data grading is proposed in this paper, enabling the quantitative classification of vehicle data. Meanwhile, the process of test verification on basis of decomposing requirements is also the subject of this paper. Tests can be derived directly from the requirements at the finest level. The coverage analysis of requirements is explored integrating the impact of data classification, requirements decomposition and test results. This paper is useful for vehicle developers to conduct development and test verification for data security requirements.
