摘要

命名数据网络(NDN)代表了未来互联网架构的主要候选信息中心网络(ICN)之一。它将数据视为中心元素,并利用网络内缓存。访问控制是这个项目的基本安全特性。它限制只有授权实体才能访问数据。但是,它不能再绑定到内容位置或特定主机,因为相同数据的多个副本可以驻留在不同的网络位置。因此,必须采用面向数据的访问控制模型。在本文中,我们提出了一种基于加密的NDN访问控制方案,该方案允许加密内容自由地驻留在网络的任何位置。该提案代表了在实际NDN原型CCNx中已经实现的解决方案的增强。它基于访问权限管理的新加密模型和对命名系统的调整。它减轻了已识别的攻击,并降低了开销成本。

Access control enforcement in Named Data Networking
Named Data Networking (NDN) represents one of the major Information Centric Networking (ICN) candidates for future Internet architectures. It treats data as the central element and it leverages in-network caching. Access control is a fundamental security feature in this project. It limits data access to only authorized entities. However, it can no longer be tied to a content location or to a particular host, since multiple copies of a same data can reside in various network locations. Therefore, a data-oriented access control model must be adopted. In this paper, we propose an encryption-based access control scheme for NDN that allows encrypted content to freely reside anywhere in the network. This proposal represents an enhancement of the solution already implemented in the actual NDN prototype, CCNx. It is based on a new cryptographic model for access rights management and on an adaptation of the naming system. It mitigates identified attacks and it reduces the overhead cost.
