物联网安全关键技术与挑战
2015
Overview
物联网是信息技术发展到一定阶段的产物, 是全球信息产业和技术的又一次飞跃. 物联网的发展非常迅速, 市场潜力巨大. 同时, 物联网的信息安全问题是关系物联网产业能否安全可持续发展的核心技术之一, 必须引起高度重视. 本文首先分析了物联网安全研究的背景和意义, 介绍了国内外在物联网方面的发展情况和重视程度, 阐述了国内的技术短板, 国家对物联网技术和产业的支持等情况, 然后基于大家熟知的物联网三层逻辑架构, 分析了物联网的安全架构, 并侧重感知层安全和应用层安全, 分析了需要研究的一些研究方向和关键技术, 并对这些技术的本质、关键问题进行了分析. 在物联网的感知层, 本文指出轻量级安全是其需求特点, 也是最主要的技术挑战, 轻量级安全技术包括轻量级密码算法和轻量级安全协议. 在物联网的应用层, 本文指出隐私保护、移动终端设备安全、物联网安全基础设施和物联网安全测评体系是关键技术. 对物联网传输层安全和处理层安全的关键技术, 本文将其分别归为网络安全和云计算安全领域, 不属于物联网专有的安全技术, 从而未作深入探讨.
