| RFID Code Resolution Service is a query service. It provides a mapping service for RFID code and the address that memory the information about the goods. RFID Code Resolution Service can be divided into two parts-Static Resolution Service and Dynamic Resolution Service. The mapping relation provided by Static Resolution Service is confirmed at the stage of distributing the code. The mapping relation provided by Dynamic Resolution Service is described as an address chain, and the chain extends with increase of information. EPC Organization has been researching a Dynamic Resolution Service-Discovery Services. Discovery Services are envisaged to provide pointers to multiple providers of information across a supply chain, to indicate the addresses of information services of all organizations that hold information about a given physical object.Because of the distributed storage for the datum provided by Discovery Service, it is difficult to confirm the security of the datum. Therefore, the thesis provides a new Supply-Chain-oriented RFID Dynamic Resolution System with the lead of 863 Project. The system aim at the characteristic of roles in Supply Chain, set the manufacturer as the organization of Information Service, and storage the information in server of manufacturer. It can provide an information-shared platform for enterprises and help them acquire information in time. It confirms the trustiness of datum using Security Authentication based centrality management.The system researches and implements a Supply-Chain-oriented RFID Dynamic Resolution System bases on RFID Code Resolution System. In order to confirm the security of the datum in Supply Chain, the system takes measures of Certificate Authorization, Digital Signature and Secure Transmission.The system can provide public query integrated with Static Resolution System. It can also provide private query for some corporation. The research of the system has a positive role in promoting application of RFID in China. |
