Using a gateway overlay network to achieve secure and scalable network interconnection

In this paper we discuss an approach to build a secure and scalable network interconnection mechanism based on a gateway overlay network for address-less, identifier-based networks. The purpose of the overlay network is twofold. First, it provides a mapping between end-node identifiers and gateway identifiers. Second, it is the mechanism used to deliver messages from one network to another. As the underlying network infrastructure, our proposal supports many network infrastructures, such as the current and future Internet.
