Research and Application of Data Privacy Protection Technology in Cloud Computing Environment Based on Attribute Encryption

摘要

With the continuous progress of Internet information technology, cloud computing has come into being. In the cloud computing environment, most applications and data are moved to the huge network data centers of cloud service providers. However, when users outsource sensitive data to cloud services, this raises a number of issues related to data security and access control. Focusing on cloud computing environment based on the weight of attribute more agencies encryption problem, this paper puts forward a cloud computing environment based on the weight of attribute more agencies encryption scheme, and by introducing concept of attribute weights, attributes authority according to the attribute importance for attributes assigned different weights. Attribute weights of attributes can be converted to set. This scheme can reflect the importance of attributes, so it has more practical significance, so as to prove the security and correctness of the cloud computing environment.
