摘要：Numerous smart card based authentication protocols have been proposed to provide strong system security and robust individual privacy for communication between parties these days. Nevertheless, most of them do not provide formal analysis proof, and the security robustness is doubtful. Chang and Cheng(2011) proposed an efficient remote authentication protocol with smart cards and claimed that their proposed protocol could support secure communication in a multi-server environment. Unfortunately, there are opportunities for security enhancement in current schemes. In this paper, we identify the major weakness, i.e., session key disclosure, of a recently published protocol. We consequently propose a novel authentication scheme for a multi-server environment and give formal analysis proofs for security guarantees.

摘要：Guided mode resonant filters （GMRFs） for authentication application with low sideband reflection at 0^o and 90^o azimuthal angles were designed. Using rigorous coupled-wave analysis, the diffractive characteristics of this kind device with different illumination angles, groove depths, and thicknesses of cover SiO2 layer were investigated. The structure of GMRF which satisfies the requirements for authentication applications was obtained. Illuminated at 30^o for a definite polarization mode, the filter presents symmetrical reflectance shape, low sideband reflectance, two separate reflectance peaks, and definite full-width at halfmaximum （FWHM） at 0^o and 90^o azimuthal angles.

摘要：基于authentication Test方法,围绕高效安全Internet密钥交换(ESIKE)协议的安全目标,提出一种具体地构建唯一满足两个通信实体变换边的形式化协议设计方法,设计出了高效安全的IKE协议;并且基于StrandSpace模型和authentication Test方法,形式化分析ESIKE协议,证明了其所具有的安全特性.该ESIKE协议克服了原有Internet密钥交换(IKE)协议存在的安全缺陷,提供了安全的会话密钥及安全关联(SA)协商,保护了通信端点的身份,并且保证了协议发起者和响应者间的双向认证.同时,ESIKE仅需3条消息及更少的计算量,更加简单、高效.

摘要：The grid technology is recognized as the next generation of Internet and becomcs the center of recent researches in the computer society. Security is one of the most crucial issues to address in Internet and is of the same importance in the application of grid technology. As a critical component of grid security, the secure authen- tication needs to be well studied. In this paper, a two-step mobile agent based（TSMAB） authentication architecture is proposed based on Globus security infrastructure （GSI）. By using mobile agent （MA） technology, the TSMAB authentication architecture is composed of the junior-authentication and the senior-authentication. Based on the design and the analysis of TSMAB model, the result shows that the efficiency of grid authentication is improved compared with the GSI authentication.

摘要：To strike a tradeoff between the security and the consumption of energy,computing and communication resources in the nodes,this paper presents an efficient authentication scheme based on one-way key chain for sensor network. The scheme can provide immediate authentication to fulfill the latency and the storage requirements and defends against various attacks such as replay,impersonation and denial of service. Meanwhile,our scheme possesses low overhead and scalability to large networks. Furthermore,the simple related protocols or algorithms in the scheme and inexpensive public-key operation required in view of resource-starved sensor nodes minimize the storage,computation and communication overhead,and improve the efficiency of our scheme. In addition,the proposed scheme also supports source authentication without precluding in-network processing and passive participation.

摘要：Biometrics technologies have been around for quite some time and many have been deployed for different applications all around the world, ranging from small companies' time and attendance systems to access control systems for nuclear facilities. Biometrics offer a reliable solution for the establishment of the distinctiveness of identity based on 'who an individual is', rather than what he or she knows or carries. Biometric Systems automatically verify a person's identity based on his/her anatomical and behavioral characteristics. Biometric traits represent a strong and undeviating link between a person and his/her identity, these traits cannot be easily lost or forgotten or faked, since biometric systems require the user to be present at the time of authentication. Some biometric systems are more reliable than others, yet they are neither secure nor accurate, all biometrics have their strengths and weaknesses. Although some of these systems have shown reliability and solidarity, work still has to be done to improve the quality of service they provide. Presented is the available standing biometric systems showing their strengths and weaknesses and also emerging technologies which may have great benefits for security applications in the near future.
