摘要
在动态联盟中,身份管理是确保信息安全的一种手段,但是随着联盟成员数日益增多,传统的身份管理难以妥善应对当前较为复杂的环境,尤其当成员之间无交互历史时,数据交换的可靠性无法保障。文中研究了不同计算环境中的多种信任管理方法,并把P2P的推荐评价机制应用到动态联盟的身份管理中,提出了一种基于推荐的身份信任管理的算法。在这种算法中,身份的信任值由多因素加权综合而成,其中推荐信任值在算法中起到关键的作用。该算法试图为解决复杂的动态联盟环境下的身份管理问题提供一种途径。
In the environment of dynamic federation, the identity management is one of the methods for security issues. However, with the increasing of the members, it is more difficult for traditional identity management to deal with the complex situation, especially when members have no communieation records, the security of data switching can not be guaranteed. Focused on some of trust management models, applying the reputation and evaluation mechanism in P2P to dynamic federation, the article brings forward an identity trust algorithm based on reputation. The algorithm, in which trust is weighted by various factors, and reputation rate is a key problem, is expected to offer one method to solve the identity management in the complex dynamic federation.
