A Study on Establishment of Secure RFID Network Using DNS Security Extension

RFID network mainly consists of three components, such as ODS(object directory service), OTS (object traceability service), OIS(object information service). The RFID information is very important, so the security between RFID network components is critical. The DNS technology already have defined the security standard such as DNS security extension & DNS dynamic update, so RFID network security can be achieved using current DNS security model. For the dynamic update of OIS URI mapping on RFID code, the DNS dynamic update technology can be used. The authentication, authorization and confidentiality need between RFID network components can be accomplished by PKI certificate system, and DNS server can be used as PKI certificate repository for the storing & retrieval of each other´s certificate. So we proposed the secure integration of RFID network components by using DNS security extensions
