Managing Delegation in Access Control Models

Meriam Ben Ghorbel-Talbi, Frederic Cuppens, Nora Cuppens-Boulahia, Adel Bouhoula

摘要:

在访问控制领域,委托是一个重要的方面,被认为是管理机制的一部分。因此,一个完整的访问控制必须提供一个灵活的管理模型来管理委托。不幸的是,据我们所知,没有一个完整的模型来描述基于角色的访问控制的所有委托要求。因此,建议的模型往往是扩展到考虑新的委托特性,这是一个复杂的任务,管理和必要的重新定义这些模型。在本文中,我们描述了一个新的委托方法扩展的基于角色的访问控制模型。我们表明,我们的方法是灵活的,足以管理所有的授权要求。

英文摘要:

In the field of access control, delegation is an important aspect that is considered as a part of the administration mechanism. Thus, a complete access control must provide a flexible administration model to manage delegation. Unfortunately, to our best knowledge, there is no complete model for describing all delegation requirements for role-based access control. Therefore, proposed models are often extended to consider new delegation characteristics, which is a complex task to manage and necessitate the redefinition of these models. In this paper we describe a new delegation approach for extended role-based access control models. We show that our approach is flexible and is sufficient to manage all delegation requirements.
