物联网在未来智能城市、智能交通系统等领域的广泛应用代表了几种具有经济、环境和社会影响的安全攻击的蓬勃发展表面。本文回顾了新兴的物联网网络面临的安全挑战，并讨论了物联网网络中基于不同领域的一些攻击及其对策。大多数传统的物联网解决方案都是从通信网络出发的，同时注意到物联网网络的节点数量、异构性和节点资源有限等特点，这些传统的安全方法是不够的。在大规模物联网中使用基于公共密钥的加密方法的一个挑战是密钥的生成、分发和存储以及保护这些密钥免受物理攻击的问题。物理不可克隆功能(PUF)可用作物联网中身份识别和认证的可能硬件补救措施。由于PUF提取了独特的硬件特征，它们潜在地为密钥生成提供了一种负担得起且实用的解决方案。然而，有几个障碍限制了PUF在密钥生成方面的应用。我们讨论了基于PUF的密钥生成方法的优点，并对该领域的最新技术进行了综述。我们还提出了一种基于概念验证PUF的解决方案，该方案使用嵌入在物联网中的电阻随机存取存储器(ReRAM)来生成密钥。
The vast areas of applications for IoTs in future smart cities, smart transportation systems, and so on represent a thriving surface for several security attacks with economic, environmental and societal impacts. This survey paper presents a review of the security challenges of emerging IoT networks and discusses some of the attacks and their countermeasures based on different domains in IoT networks. Most conventional solutions for IoT networks are adopted from communication networks while noting the particular characteristics of IoT networks such as the nodes quantity, heterogeneity, and the limited resources of the nodes, these conventional security methods are not adequate. One challenge towards utilizing common secret key-based cryptographic methods in large-scale IoTs is the problem of secret key generation, distribution, and storage and protecting these secret keys from physical attacks. Physically unclonable functions (PUFs) can be utilized as a possible hardware remedy for identification and authentication in IoTs. Since PUFs extract the unique hardware characteristics, they potentially offer an affordable and practical solution for secret key generation. However, several barriers limit the PUFs' applications for key generation purposes. We discuss the advantages of PUF-based key generation methods, and we present a survey of state-of-the-art techniques in this domain. We also present a proof-of-concept PUF-based solution for secret key generation using resistive random-access memories (ReRAM) embedded in IoTs.
