In sensor network there are no nodes or servers that are exclusively responsible for packet forwarding and routing. Instead, sensor nodes participating in network communications perform these activities. Thus, they are vulnerable to the alteration and forgery of message in the process of packet forwarding and routing. To solve this problem, a security to ensure authentication and integrity of routing...
In this paper, we propose an RFID authentication protocol that enforces user privacy and protects against tag cloning. Our scheme is based on the use of a secret shared between tag and database that is refreshed to avoid tag tracing. Additionally, our protocol is very simple and it can be implemented easily with the use of standard cryptographic hash functions.
In order to overcome the drawbacks and combine the advantages of both 3G packet-switched mobile communication systems and WLAN, wireless broadband Internet (WiBro) system based on 2.3 GHz bandwidth and IEEE 802.16e has been developed in Korea. Recently, the new version of WiBro system, named WiBro-evolution (WiBro-EVO) system which provides various multimedia services, is researched. In this paper,...
