Abstract: The data interaction of desktop virtualization between internal application data and external user operation platform are realized by virtual desktop protocol.Because of the deficiency of the data flow control mechanism in this kind of protocol,it may lead to the illegal interaction.In order to resolve this problem,based on gateway,this paper proposed a secure control mechanism of internal and external data-flow oriented to virtual-desktop.It not only has the overall control of virtual channel,avoiding modifying lots of transport protocols or terminals,but also has high compatibilities,expansibilities and usability.Deploying it at the gateway to protect from boundaries attack can reduce the server load and safety concerns significantly.Experiments prove that this mechanism can control the direction of data flow effectively.Meanwhile,it has little impact on existing desktop session.

Key words: Desktop virtualization,Virtual desktop protocol,Secure control mechanism,Internal and external dataflow
