Research and design of universal plug and play device access control and security protocol

The UPnP protocol has been more and more applied to the local area network and the family of intelligent network.But the security problems which UPnP brings are paid more and more attention,and the relevant solutions of UPnP security problems are very little.Based on the introduction of UPnP composition and processes at the same time,we also analyze the security problems which UPnP easy to cause.And then the author provide a security protocol which uses the security console to control the device access and uses the encryption transmission between the control points and device.This security protocol can effectively protect the integrity of the data,protect data keep from bluff it,and prevent heavy hair attack,etc.
