基于命名数据网络的安全机制研究

摘要

对命名数据网络体系结构提出的背景进行描述,针对当前互联网网络体系结构存在的安全问题,对命名数据网络体系结构中的安全特点进行介绍,重点研究命名数据网络的安全机制,主要集中于签名及认证、信任关系的管理机制、基于命名的访问控制等方面,同时研究其与传统网络安全体制的区别,并对其在医疗、工业控制等领域的应用进行描述,探讨命名数据网络安全机制面临的一系列问题和挑战.%Background for naming data network architecture is described, in view of security problems in Internet architecture, the security characteristics of named data network system structure are presented. This paper mainly describes the security mechanism of named data network, with focus on the management mechanism of signature and authentification, trust relationship,and named access control, and meanwhile explores the difference of between this system and the traditional network security system, including its application in the field of medical and industrial control. In addition, various problems and challenges faced by the named data network security mechanism are also discussed in this paper.
