OTP and user behavior-based certification and authorization method in mobile cloud computing environment

Abstract

The present invention discloses an OTP and user behavior-based certification and authorization method in a mobile cloud computing environment. The method is characterized in that various intelligent mobile terminals available for users are enabled to be accessed to the cloud service via a wireless network in the mobile cloud computing environment and the bidirectional identity authentication between a client and a server is realized through improving the one-time password (OTP) technology. In this way, the safety and the reliability of the identity authentication process are improved. Meanwhile, according to the specific behavior habits of a user accessed to the cloud service, the features of historical behavior data of the user are analyzed and extracted based on the data mining technology. In this way, a knowledge database of the normal behavior patterns of the user is formed. When the user behaves abnormally or suspiciously, the identity of the user is authenticated again. Only when the user passes the identity authentication process, the corresponding service is authorized for the user. Therefore, the illegal operation of others is avoided, and the information security of the user is fully ensured.

Description

technical field The invention belongs to the field of cloud computing security, in particular to an authentication and authorization method based on OTP and user characteristics in a mobile cloud computing environment. Background technique Since Google proposed the concept of mobile cloud computing in 2006, various services and platforms related to cloud computing have appeared in people's field of vision, and cloud services have become more and more popular due to their convenience, scalability, and savings. , users can store and calculate information in the cloud, which reduces many constraints caused by limited storage and computing resources. With the widespread use of various smart terminals such as smartphones and tablet computers in people's daily life, various mobile cloud computing services based on smart terminals have also emerged correspondingly, enabling users to use various cloud services through wireless networks. However, the following cloud security issue...
