Immobilizer Implementation using Mutual Authentication with Enhanced Security using 802.15.4 Protocol .

Zigbee is a wireless technology that utilizes radio communication with 802.15.4 an IEEE standard. Presently, the widespread deployment of RFID technologies may generate new threats to security and user privacy. One of the main drawbacks of RFID technology is the weak authentication systems between reader and a tag. In general, “weak” authentication systems that either leak the password directly over the network or leak sufficient information while performing authentication allow intruders to deduce or guess the password. In this paper, we study the Zigbee based mutual authentication scheme. A hardware implementation of the mutual authentication protocol for the RFID system is proposed. The proposed system was implemented using a general purpose micro controller 89c51. The system has been successfully implemented in hardware using two zigbee transievers.
