Research on the implementation of secure UPnP architecture

Universal plug and play, or UPnP in short, is a ldquoplug and playrdquo methodology used in network environment. It´s designed to share resources, connect network devices and offer control over services. It implements zero-configuration. Developer can save the cost of network setup and concentrate on the offering services only and do not need to concern the under layer protocol. As the wide spreading of UPnP protocol, building a secure UPnP system is becoming more important. The paper introduces a secure UPnP architecture based on the UPnP network and implements the protocols and algorithms of the secure architecture. It is different from create a secure communication channel point to point based on the UPnP devices. We adopted the decentralized mechanisms for key management, analysed the limits of our protocol and proposed the corresponding measures. Finally, we compared with two important protocols using decentralized key management mechanisms, stated their limits and solutions of our scheme.
