一些无线传感器网络排除了持续存在的集中式数据收集点，即接收器。在这样的断开连接或无人值守的设置中，节点必须累积感测到的数据，直到它可以被卸载到巡回接收器。此外，如果操作环境是敌对的，则存在节点和数据泄露的非常真实的危险。网络的无人值守性质使其成为旨在学习、删除或修改传感器收集和保存的潜在有价值数据的攻击的有吸引力的目标。我们认为，对抗模型和防御技术在以前的无线传感器网络的安全文献是不适合无人值守的无线传感器网络设置。我们定义了一个新的对抗模型，考虑到特殊功能的UWSN环境。我们表明，在一个强大的移动的对手的存在下，保护存储在无人值守的传感器上的数据提出了有趣的挑战，并开辟了一个令人兴奋的新的研究领域。
Some wireless sensor networks preclude the constant presence of a centralized data collection point, that is, a sink. In such a disconnected or unattended setting, nodes must accumulate sensed data until it can be off loaded to an itinerant sink, Furthermore, if the operating environment is hostile, there is a very real danger of node and data compromise. The unattended nature of the network makes it an attractive target for attacks that aim to learn, erase, or modify potentially valuable data collected and held by sensors. We argue that adversarial models and defense techniques in prior WSN literature about security are unsuitable for the unattended WSN setting. We define a new adversarial model by taking into account special features of the UWSN environment. We show that in the presence of a powerful mobile adversary, securing data stored on unattended sensors presents interesting challenges and opens an exciting new line of research.
