An RFID system generally consists of tags, readers, and backend servers with the readers charged with authenticating/identifying the tags with the help of the servers. Two important enhancements have been suggested for widespread adoption of RFIDs, namely the use of low cost (5?? or less) passive RFID tags and serverless system design to overcome the need for persistent connection between the readers...
Wireless access points largely fall into three categories: home and small business networks, enterprise networks, and hotspots. Wi-Fi Protected Access (WPA) provides solutions to home, small business, and enterprise networks, but hotspots typically are not secured at the Medium Access Control (MAC) layer because they are open to the public. In this paper, we present a scheme that establishes a secure...
The emerging vehicular communications will enable a variety of applications for safety, traffic efficiency, driver assistance and infotainment. Due to high vehicular speed, sporadic connection, limited communication range, and large volume of data that need to be transmitted, vehicular communications have the crucial requirements of fast authentication and encryption/decryption. This paper addresses...
Wireless body sensor networks (BSN) are being used to continuously monitor the patient's conditions and recovery progress. It is very important to secure the confidentiality, integrity and authenticity of the patient's health record in such applications. In this paper, we propose a novel key distribution and management scheme that uses keychains to establish group keys for body sensor networks. This...
