最近基于无线的通信技术和电子技术的进步促进了低成本、低功耗传感器网络的实现。基本上，无处不在的传感器网络（USN）由三部分组成:由大量传感器节点组成的传感器网络、连接传感器网络和应用服务器的基站（也称为网关），以及控制传感器网络中传感器节点或从传感器网络中的传感器节点收集感测信息的应用服务器。 ISO/IEC 29180:2012描述了USN的安全威胁和安全要求。此外，它根据满足上述安全要求的安全功能以及安全技术在USN安全模型中的应用，对安全技术进行分类。 最后，介绍了USN的安全功能需求和安全技术。

The recent advancement of wireless-based communication technology and electronics has facilitated the implementation of a low-cost, low-power sensor network. Basically, a ubiquitous sensor network (USN) consists of three parts: a sensor network consisting of a large number of sensor nodes, a base station (also known as a gateway) interfacing between the sensor network and an application server, and the application server controlling the sensor node in the sensor network or collecting the sensed information from the sensor nodes in the sensor network. ISO/IEC 29180:2012 describes the security threats to and security requirements of the USN. In addition, it categorizes the security technologies according to the security functions that satisfy the said security requirements and where the security technologies are applied in the security model of the USN. Finally, the security functional requirements and security technologies for the USN are presented.
