摘要

预先义务是指在授予访问权之前可能需要采取的行动。预义务的成功完成将授权所请求的访问。因此,义务诱导义务和授权策略状态之间的交互。本文通过形式化支持前置义务时授权和义务状态的演变来研究这些相互作用。所提出的方法的主要优点是,预先义务是基于谓词逻辑的声明性语义和基于事件-条件-动作(ECA)规则的操作语义。此外,所提出的框架使策略设计者能够轻松地选择评估任何预义务:(1)静态地(如果未履行预义务,则拒绝访问请求);(2)或动态的(在请求访问之后和授权访问之前,给予用户履行预义务的可能性)。

From Contextual Permission to Dynamic Pre-obligation: An Integrated Approach
Pre-obligations denote actions which may be required before access is granted. The successful fulfillment of pre-obligations authorizes the requested access. Thus, preobligations induce interactions between the obligation and authorization policy states. This paper studies these interactionsby formalizing the evolution of the authorization and obligation states when pre-obligations are supported. The main advantage of the presented approach is that pre-obligations are given both declarative semantics based on predicate logic and operational semantics based on Event-Condition-Action (ECA) rules. Furthermore, the presented framework enables policy designers to easily choose to evaluate any pre-obligation either(1) statically (an access request is denied if the pre-obligation has not been fulfilled); (2) or dynamically (users are given the possibility to fulfill the pre-obligation after the access request and before access is authorized).
