标题： Securing IoT Devices in Smart Cities: A Review of Proposed Solutions

摘要： 在智慧城市中，由于物联网（IoT）设备引入的漏洞，隐私和安全始终面临持续的风险。 这些设备有限的计算资源使它们特别容易受到攻击，而它们的广泛应用则增加了安全漏洞的潜在影响。 本文回顾了旨在保护智慧城市环境中物联网设备的安全方案。 本次回顾是通过分析最近关于设备级安全的文献进行的，特别强调轻量级密码学、物理不可克隆函数（PUFs）以及基于区块链的解决方案。 研究结果突显了当前方法的优势和局限性，以及需要更多实用、可扩展且资源高效的机制，以确保物联网生态系统中的用户隐私和数据保护。 显示英文摘要

摘要： Privacy and security in Smart Cities remain at constant risk due to the vulnerabilities introduced by Internet of Things (IoT) devices. The limited computational resources of these devices make them especially susceptible to attacks, while their widespread adoption increases the potential impact of security breaches. This article presents a review of security proposals aimed at protecting IoT devices in Smart City environments. The review was conducted by analyzing recent literature on device-level security, with particular emphasis on lightweight cryptography, physically unclonable functions (PUFs), and blockchain-based solutions. Findings highlight both the strengths and limitations of current approaches, as well as the need for more practical, scalable, and resource-efficient mechanisms to ensure user privacy and data protection in IoT ecosystems.
