Wireless Network Communication has been a popular research area recently, among the technologies, ZigBees has been known to its low-cost and low power consumption features. In addition to its low-cost and low power consumption features, ZigBee provides more secured methods in data authentication and encryption for security aspect, such as CMM* model: Link-Key, Network-Key, and AES-CCM-128 algorithm to encrypt data in point-to-point communication to protect systems from various attacks. Further, ZigBee plays trusted center role through Full-Functional Device (FFD) in network environment, manages encrypted keys creation and distribution with other points and provide the function of cross certificate between network devices by utilizing SKKE protocol. This study utilizes passive RFID tags, mutual authentication, secure accesses to RFID and low computation cost and low communication cost properties to achieve integration between different types of networks. The study divides the authentication flow into three stages: registration, sign-on and key exchange and mainly uses the built-in security feature of ZigBee to add on the security authentication mechanism of RFID which most investigated in the issues of cross certificate and data security between RFID readers and RFID tags. By integrating ZigBee’s SKKE protocol and CMM* encryption and decryption modes with mechanism proposed by previous works, we extend the authentication mechanism originally only between RFID readers and RFID tags to RFID readers and back-bone server. Eventually, all the data from back-bone sever through RFID reader to RFID tag can be cross authenticated and meet the encrypted data transferring mechanism by distributed keys from ZigBee trusted center and SKKE protocol.
