With the growing maturity of cloud computing and the wider application range, deploying applications on cloud computing platform has become a common way in the Internet industry. The user privacy of cloud server has also become the focus of attention. It is difficult for application providers to fully control the data stored on the cloud server, which increases the possibility of user privacy disclosure. In this paper, we propose a dynamic Token-D model to distribute authentication token of client and cloud server, which uses a third-party server to store user information and generate dynamic tokens. The client and cloud server achieve dynamic tokens to manage login authentication and information interaction. The experimental results verify the feasibility of the model, which can effectively protect the privacy of users a degree. |
