Abstract: For the cloud desktop access control problems, put forward a virtual cloud desktop access control algorithm based on statistics, the virtual desktop cloud data encryption processing and the process of the encryption is analyzed, on this basis, through the establishment of virtual cloud desktop access concurrent user load of queuing theory model, and analyses the virtual cloud desktop access control algorithm based on statistical process, so as to complete the access control, in that users access requirements at the same time, using virtual desktop cloud resources to the greatest extent. Experiments show that the proposed access control algorithm can effectively guarantee the safety of the virtual desktop cloud data and improve the response time of the access control, and access control precision is higher.
