At the same time identity and password based authentication schemes are no longer adequate because of the insecurity of user identity and password. As a result biometric user authentication has emerged as a more reliable and attractive method. However, existing biometric authentication schemes are vulnerable to some common attacks and provide no security proof, some of these biometric schemes are also either inefficient or lack sufficient concern for privacy. In this paper, we propose an anonymous and efficient remote biometric user authentication scheme for a multi-server architecture with provable security. Through theoretical mathematic deduction, simulation implementation, and comparison with related work, we demonstrate that our approach can remove the aforementioned weaknesses and is well suited for a multi- server environment.展开更多

With the purpose of using various different internet services with single registration and to protect the users from being tracked, various dynamic ID based multi-server authentication protocols have been proposed. Recently, Li et al. proposed an efficient and secure dynamic ID based authentication protocol using smart cards. They claimed that their protocol provides strong security. In this paper, we have demonstrated that Li et al.’s protocol is vulnerable to replay attack, denial of service attack, smart card lost attack, eavesdropping attack and server spoofing attacks.展开更多

In the scheme,an embedded microprocessor( LPC3250 from NXP) is chosen as the CPU of the embedded server with a linux operation system( OS) environment. The embedded server provides multiple interfaces for supporting various application scenarios. The whole network is based on local area network and adopts the Browser / Server( B / S) model. The monitoring and control node is as a browser endpoint and the remote node with an embedded server is as a server endpoint. Users can easily acquire various sensors information through writing Internet protocol address of remote node on the computer browser. Compared with client / server( C / S) mode,B / S model needs less maintain and can be applicable to large user group. In addition,a simple network management protocol( SNMP) is used for management of devices in Internet protocol( IP) networks. The results of the demonstration experiment show that the proposed system gives good support to manage the network from different user terminals and allows the users to better interact with the ambient environment.展开更多
