Abstract

This paper compares and contrasts authentication mechanisms used in three VO architectures: the first reflects ad-hoc connections among several organizations, the second uses a centrally managed database and the third is based on public key infrastructure (PKI). The reason for studying these particular three architectures is that they cover a large class of currently operating VOs (i.e. supply chains, grids). These architectures used several types of authentication mechanisms starting from traditional username/password, through online trusted servers (Kerberos), to offline trusted third parties: certificate authorities and digital certificates. The current defacto-standard middleware used to build VOs, Globus toolkit, is based on the PKI architecture.
虚拟组织三种架构中身份管理的比较与评价
本文比较和对比了三种VO体系结构中使用的身份验证机制:第一种反映了几个组织之间的临时连接,第二种使用集中管理的数据库,第三种基于公钥基础设施(PKI)。研究这三种架构的原因是,它们涵盖了当前运行的VOs(即供应链、电网)的一大类别。这些体系结构使用几种类型的身份验证机制,从传统的用户名/密码开始,通过在线可信服务器(Kerberos),再到离线可信第三方:证书颁发机构和数字证书。目前用于构建VOs的实际标准中间件Globus工具包是基于PKI体系结构的。
