| 摘 要： | 信任管理(TM)是面向开放多域环境的分布式授权技术。TM系统从网络中搜索委派凭证以进行分布式授权决策,面临效率和可用性问题。本文提出一种基于SPKI的分布式凭证存储框架,将委派凭证冗余地存储到相关实体,以避免委派凭证的动态搜索过程,有助于解决现有TM系统凭证管理的局限性。

| Abstract: | Trust Management (TM) is a distributed authorization technology for open multi-domain environments. TM systems search delegation credentials from the network for making distributed authorization decisions,which is not efficient and highly available. This paper proposes a distributed credential management framework,which stores delegation credentials redundantly at relevant entities to avoid dynamic search processes of delegation credentials.Our approach is helpful in overcoming the limitations of the creden... |
