The mobile payment refers that the transactions are realized by mobile terminals, such as a mobie phone, PDA, mobile PC and so on. This paper proposes a hash-chain based small money payment system which guarantees an anonymity of user by secret signing one time in the procedure of withdrawing route value through RFID-USB module for a mobile user who receives IPTV weddingTday service to increase convenience...
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...
As the degree of dependency and application of component increases, the need to strengthen security of component is also increased as well. The component gives an advantage to improve development productivity through its reusable software. Even with this advantage, vulnerability of component security limits its reuse. When the security level of a component is raised in order to improve this problem,...
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 2.3GHz bandwidth and IEEE 802.16e developed in Korea. Recently, the new version of WiBro system, named WiBro-evolution (WiBro-EVO) system which provides higher performance and various multimedia services, is being developed...
In this paper, the eigenface-based fuzzy vault scheme, called a fuzzy eigenface vault, is designed and examined, and authentication protocol using the fuzzy eigenface vault is designed based on a smartcard and analyzed security of the proposed authentication protocol. Especially, face recognition for user authentication has several advantages such as natural, nonintrusive, convenience, and easy to...
