分布式信任模型在电子商务中的应用

A Distributed Trust Model for E-Commerce Applications

本文提出一个通用的，并可以独立使用的动态分布式信任模型（DDTM）。在DDTM中，访问权限直接与信任值相关联。信任值又具体分为直接信任值、间接信任值和信任授权等级。文中已经计算并将每一类型的信任价值用明确的数字形式表示。这个模型的核心是基于推荐的信任模型，被组织成信任授权树（TDT），并以证书链的形式进行授权。

There is a general purpose, application-independent Dynamic Distributed Trust Model （DDTM）.In DDTM, access rights are directly associated with a trust value. The trust values are further classified into direct trust values, indirect trust values and trust authorization levels. We have calculated and expressed each type of the trust values into explicit numerical numbers. The core＇of this model is the recommendationbased trust model, organized as a Trust Delegation Tree （TDT）, and the authorization delegation realized by delegation certificate chains.
