Secret Searching in Wireless Sensor Networks with RFIDs

In this paper, we propose a network architecture with RFIDs and sensor nodes (ARIES), a mutual authentication protocol (AMULET), and a secret search protocol (ASSART). In ARIES, the distance limitation can be relieved with the help of widely deployed RFID-aware sensor nodes. AMULET can perform mutual authentication and reduce the cost for re-authentication. ASSART solves the privacy problem by offering a secret search mechanism over encrypted data. In this way, data will not be disclosed during communication and query processes.
