Wu Zhengxue wears red

The security and privacy protection of data poses a great challenge to the cloud computing field, and an access control technique based on negative rules is proposed to realize the sharing of some data among cooperative enterprises in the cloud environment without involving confidential information. The main idea is to prevent illegal access by judging whether the access query is authorized and whether there is conflict between the authorization and the negative rule. Theoretical analysis and experimental results show that this mechanism can effectively guarantee the security of cloud data.
