英文摘要： To solve the problem of privacy disclosure during the process of network access, data acquisition and service application in the intelligent transportation cloud, this project mainly concentrates on key technologies of privacy protection in this environment. On the one hand, based on the characteristics of intelligent transportation cloud, such as network heterogeneous and varied terminal performance, this project researches general anonymous authentication and key management technology, and provides fundamental support and protection of user privacy in access layer.On the other hand, based on users' daily application, this project researches possible solutions of privacy protection during the process of data acquisition and service application, with an emphasis on users' identity protection mechanism based on the combination of special signatures and aliases, and users' interest protection mechanism based on homomorphic refactoring and sorting. Finally, this project proposes a comprehensive scheme for user privacy protection. The project emphasizes the sustainability and portability of research, theoretical and technical prospective and the effectiveness of applications.
