面向物联网IP核保护的轻量化认证

针对物联网设备和应用的低功耗、微型化等特点,利用物理不可克隆函数和有限状态机模型,提出一种安全且轻量化的认证方案,不仅可以有效地避免面向物联网的IP核被克隆和物理攻击,而且可以防止IP核的盗用和滥用。认证方案以两种混合的物理不可克隆函数为基础,采用三级有限状态机设计,具备错误纠正机制,目的是在不使用复杂计算和不消耗大量硬件资源的前提下,保证物联网设备和应用中的IP核安全并缩减时序复杂度,同时还可以对IP核进行授权使用。实验结果表明,对比已有的一些IP核保护策略,该方案在面积和功耗等轻量化属性上具有较为明显的优势。

Lightweight authentication mechanism for IP protection of IoT

This paper proposes a secure and lightweight authentication mechanism, which is signed with the physical unclonable functions (PUF) and finite state machines (FSM), because of the characteristics of low-power and micromation of the Internet of Things (IoT) devices and applications. The model can protect intellectual property (IP) cores from cloning, physical attacks, unauthorized user access, and misuse. The three-level FSM is used to design the authentication with error correction, based on two kinds of hybrid PUF. The goal is to protect IP cores in IoT devices and applications, to reduce the time complexity without using any complex algorithms and huge hardware resources, and to authorize the use. Experimental results show that the lightweight properties such as area and power consumption have obvious advantages compared with existing IP protection.
