| 英文摘要: |
| To resolve the problem of quantitative analysis in hybrid cloud, a quantitative analysis method, which is based on the security entropy, is proposed. Firstly, according to the information theory, the security entropy is put forward to calculate the uncertainty of the system’s determinations on the irregular access behaviors. Secondly, based on the security entropy, security theorems of hybrid cloud are defined. Finally, typical access control models are analyzed by the method, the method’s practicability is validated, and security and applicability of these models are compared. Simulation results prove that the proposed method is suitable for the security quantitative analysis of the access control model and evaluation to access control capability in hybrid cloud. |
