用户认证

• The module of customer certification adds one - off password certification to the traditional sheet certification , and replaces stored password with stored digest of user password to guard against attacks and keep secrets
  用户认证模块在传统基于表单认证的方式上增加一次性口令认证，并且在密码存储时以存储用户密码消息摘要替代密码本身，从而达到防攻击和保密的目的。
• 3 ) user authentication based on keystroke features . database security is meaningless if the password is stolen . current approach for authentication based on biometrics must be supported with special hardware device with high expense
  3 )基于击键特征的用户认证机制。针对一旦口令失窃，数据库安全就无从谈起。而现有的各种生物认证技术又需要特殊的硬件支持，价格昂贵。
• As the user - identification has been gradually employed in pop3 server , the paper analyzes the base 64 and quoted - printable coding , which are extensively used to handle the disordered codes in e - mails
  随着pop3服务器逐渐使用用户认证，本文详细分析了md5算法的原理和过程。详细讨论了电子邮件常用的base64编码、 quoted - printable编码方法，运用它们可以解决电子邮件中出现乱码的问题。
• The paper presents brief introduction to the architecture , the way to construction and technical specification of authentication / accounting system . detailed illustrations are given regarding current radius protocol used in remote authentication dial in user service
  本文介绍了基于nas的网络认证计费系统的结构、组网方式和技术体制，对当前用于远程拨入用户认证服务的radius协议做了详细说明。
• In the data communication design , the paper illurstrates the implementation of the communication between internal network and external network , including the implementation of arp , network address translation , ip data collection , user authentication and packets filtering
  数据通信模块的设计中，详细介绍了内部网与外部网数据通信的实现，包括地址解析协议的实现、网络地址转换、流量数据采集、用户认证及数据包的过滤。
• - in order to control the accessing right of users and resist menace from intranet , the paper improves on a serial of linux _ based network functions and finishes design of the user ' s access control system by combining password and ip , thereby achieves access control for users
  本文在linux内核级防火链的基础上，进行一系列改进和功能增强，完成基于口令和ip地址相结合的用户认证访问控制系统的设计，从而实现了对内部用户的访问控制。
• We decided to use ibm directory services for user authentication so we could eventually implement single sign - on on the system authentication using ids is optional ; during installation you can also elect to store user authentication details in db2
  我们决定使用ibm目录服务（ ibm directory services ， ids ）进行用户认证，这样我们就可以最终在系统上实现单点登录（使用ids进行认证是可选的；在安装过程中您还可以选择在db2中存储用户的认证细节） 。
• The edicle focuses on pkl architecture , certificate path building and validation , establishment of the reliable and confidential link between ca and ra , development of ca ' s user authentication and authorization module through extending jaas ( java authentication and authorianion service ) frame
  并且着重讨论了如何扩展java的认证与授权服务来为ca的建设提供灵活可靠的用户认证和授权系统，如何利用java来方便并且安全的在ca ra之间传递信息。
• The other one is pppoe ( point - to - point protocol over ethernet ) , which is fit for adsl ( asymmetric digital subscriber line ) users . we succeeded in the control of the switch ports and the traffic accounting under dhcp mode , and in the user ' s authentication , authorization and accounting under pppoe mode
  本文给出了在宽带网上采用radius (远程拨号用户认证服务)协议结合pppoe (以太网上的点对点协议)实现用户鉴别、授权和计费管理的解决方案和实现方法。
