Radio-frequency identification (RFID) technologies are making their way into retail products, library books, debit cards, passports, driver licenses, car plates, medical devices, and so on. The widespread use of tags in traditional ways of deployment raises a privacy concern: they make their carriers trackable. To protect the privacy of the tag carriers, we need to invent new mechanisms that keep...
In this paper, we proposed an integrated biometric-based security framework for wireless body area networks, which takes advantage of biometric features shared by body sensors deployed at different positions of a person's body. The data communications among these sensors are secured via the proposed authentication and selective encryption schemes that only require low computational power and less...
This paper investigates the use of second-generation radio frequency identification (2G-RFID) technology to enable better quality of service in future networks. With encoded rules as mobile codes stored in radio frequency identification (RFID) tags, the system extendibility and practicability can be effectively improved. However, due to the openness of the mobile codes, the realization of conveying...
Wireless sensor networks (WSNs) have been widely used in a wide variety of applications. Deploying WSNs in unattended environments can cause various security threats. In these scenarios, provisioning user authentication is a critical issue. In this paper, we propose improved robust user authentication scheme for WSNs, which is a variation of strong-password based solution. We have analyzed security...
With the rapid development of wireless communication, mobile users are able to manually switch their network interfaces to different types of networks. The IEEE 802.21 Draft Standard was proposed to integrate the Media Independent Handover (MIHs) between the wireless network interfaces, such as WiFi, WiMAX, 3 GPP, and 3GPP2. However, it may not hold the seamless roaming character and does not provide...
Mobile WiMAX (IEEE 802.16e) is an emerging technology for wireless broadband access network. It provides wider converge and higher bandwidth than conventional wireless technologies. Multicast and Broadcast (M&B) in WiMAX are suitable for multimedia applications such as Pay-TV system because multimedia providers can efficiently distribute the same contents to the users within the same M&B group...
