DACPCC:一种包含访问权限的云计算数据访问控制方案
DACPCC:A Data Access Control Scheme with Access Permission for Cloud Computing
摘要
Abstract
Currently,the most common encryption scheme of cloud computing access control system is CP-ABE,but the conventional CP-ABE encryption did not deal with the issue of user's access permission;data owners only allow the users to read the data but not to write,such kind of coarse access control mechanism is not flexible and low efficiency.To deal with this issue,the paper proposes a Data Access Control scheme with access Permission for Cloud Computing (DACPCC),it sets permission control keys to encrypt the data in cloud based on CP-ABE;the data owner controls the data's access permission by choosing the permission control keys.The paper illustrates the design details of the proposed scheme,then theoretically proves the security and evaluates the performance through simulated experiments;the results show that DACPCC allows the data owners to control the access permission of the data,and it is safe and more efficient.关键词
