Abstract: A geographical identification forwarding method for area-oriented addressing. The geographic location information is used as a transmission identification, and the communication process based on the geographical identification is realized by constructing the SDN-based geographical identification transmission architecture. In this method, a geographical identification is used instead of a traditional IP identification for network transmission, which effectively alleviates the problem of narrow waist of IP single bearing in the current network. At the same time, through a flow table decomposition design, the flow table size of the switch is effectively controlled. The method provided by the present invention can be extended to a plurality of geographical identification areas to realize large-area real-time cross-domain transmission. The method is simple to operate, easy to realize and high in real-time; the method has a wide application range, and can be used to build new networks and improve network performance.

The method utilizes lightweight operations of the physical unclonable function, Hash operation, XOR operation, etc. for bidirectional authentication between an authentication server and an Internet of Things resource-limited device, and particularly utilizes uniqueness of an integrated circuit (IC) physical microstructure created by the physical unclonable function in the resource-limited device in a manufacturing process to design an engineering-implementable information desynchronization recovery mechanism of two authentication parties by optimizing an interaction mode of input challenge and output response of the physical unclonable function, thereby solving the problem that the same lightweight identity authentication type solution cannot ensure forward security and resist desynchronization attack, further reducing resource cost for an identity authentication process, and effectively improving security and operation efficiency of identity authentication of the Internet of Things resource-limited device.

Abstract: A polymorphic network control system and a polymorphic network control system method supporting terminal mobile access. A network architecture is redesigned based on the idea of separation of an identifier from a locator. In this network mode, the three-layer protocol is no longer a traditional IP message, but a message carrying a locator and an identifier. The polymorphic SDN network controller is responsible for forwarding the data packet to a destination corresponding to a destination locator. When the network location of a mobile device is changed, the transmission connection established based on the identifier will suspend communication due to the disconnection of the physical link. When the mobile device is re-accessed and a new forwarding path is established, the transmission connection can recover communication.
