Research on Hierarchical P2P Based RFID Code Resolution Network and Its Security

In order to build large-scale RFID applications, it is necessary to establish public RFID service infrastructure, the essential task is to build efficient and secure RFID code resolution network. Aiming at alleviating the problems in load balancing, single node failure tolerance and security of resolution network, based on related standards and research works, a hierarchical P2P based RFID code resolution network structure is proposed, k-Nearest Neighbor storing and hierarchical querying mechanism are presented in static resolution, secondary indexing and hierarchical querying mechanism are presented in dynamic resolution, double random number based entity and message authentication mechanism is given for the correctness of resolution service. Based on modified Kademlia, RFID code resolution services and related security mechanism are implemented. In experiments, the availability, load balancing and single node failure tolerance of our resolution network are verified.
