摘要
物联网(IoT)和信息物理融合系统(CPS)作为下一代网络的核心技术,被业界广泛关注。与传统网络不同,IoT/CPS异构融合、协同自治、开放互连的网络特性带来了巨大的系统安全方面的挑战。挑战包括安全协议的无缝衔接、用户隐私保护等。研发新的安全模型、关键安全技术和方法是IoT/CPS发展中的重点。文章基于IoT/CPS安全需求和威胁模型,提出了一种层次化的安全体系结构,并针对隐私保护、跨网认证和安全控制等IoT/CPS的关键安全技术展开讨论。
Internet of Things（IoT） and Cyber-Physical Systems（CPS） are core technologies of next generation networks,and are the focus of research in both academia and industry.IoT/CPS has unique characteristics including heterogeneous integration,collaborative autonomy,and open interconnection that raise a number of issues for system security.These issues include seamless connection between security protocols,and preservation of user privacy.Developing novel security models,key technologies,and approaches is therefore critical in the development of IoT/CPS.This paper proposes an hierarchical security architecture based on threat analysis and security requirements and discusses key technologies associated with privacy preservation,secure control,and cross-network authentication.
