The articles in this special section focus on system requirements for security, privacy, and trust for the Internet of Things (IoT). IoT has huge potential to push monitoring, computing, and communication deeply into the home, the workplace, medicine, manufacturing, and critical infrastructure. This increased capability offers the hope that urban settings can be transformed in various ways through the innovative deployment of IoT devices. Driven by a decline in the cost of sensors, many cities have adapted a plan to transition services toward being a fully smart city by implementing real-time data-driven management services across urban systems, including efficiently managing water, energy, waste, policing, and transportation among other citywide services. Cities continue to attract new people and the United Nations (UN) estimates that by 2030, more than 60% of the global population will live in large cities.1 With nearly 38 million people, Tokyo tops the UN’s ranking of most populous cities, followed by Delhi, Shanghai, Mexico City, São Paulo, and Mumbai.

物联网中安全性，隐私和信任的要求[来宾编辑介绍]

本特殊部分中的文章重点介绍物联网（IoT）的安全性，隐私和信任的系统要求。物联网具有巨大的潜力，可以将监视，计算和通信深入到家庭，工作场所，医疗，制造和关键基础设施中。这种增强的功能使人们希望通过创新部署IoT设备以各种方式改变城市环境。在传感器成本下降的推动下，许多城市通过在整个城市系统中实施实时数据驱动的管理服务，包括有效地管理水，能源，废物，治安，以及其他全市范围的服务中的运输。城市继续吸引新人，联合国（UN）估计，到2030年，
