基于物理不可克隆函数的智能警务设备认证协议

摘要

With the development of Internet of Things,sensor,and intelligent operating system,new intelligent police devices has become emerging smart terminals for realizing police’s data real-time perception,efficient processing and intelligent analysis.Due to the openness of wireless link and the sensitivity of police data,interactions between police devices and terminals (e.g.smart phones)confront serious security threats.Thus,an authentication protocol for intelligent police equipment based on physical unclonable function is designed to secure that data transmission and mutual authentication are accordingly achieved. Meanwhile, this protocol introduces lightweight secret segmentation,HMAC function,and dynamic updating mechanisms for cyber-physical security,and it is suitable for resource-constrained intelligent police device applications.%随着物联网、传感技术和智能操作系统的发展，新型的智能警务设备可以实现警务数据的实时感知、高效处理和智能分析。由于无线通信链路的开放性和警务数据的敏感性，智能警务设备与终端的数据交互面临着严峻的安全威胁。面向智能警务终端设备设计一种基于物理不可克隆函数的安全认证协议，实现智能警务设备与终端之间的安全数据传输和双向身份认证。同时，该协议引入密值分割、HMAC 函数、动态更新等轻量级安全机制，实现信息物理安全有机结合，适用于资源受限的智能警务设备应用场景。
