在过去的几十年里，usasn获得了很多关注。基于卓有成效的研究和开发，UASN未来可能成为全球物联网的一个引人注目的组成部分。从位置隐私保护的角度来看，目前的研究主要集中在usasn基础设施上，主要关注基础设施的源位置隐私保护，如锚节点、定位节点和通信信道安全。然而，在物联网场景下，usasn提供的水下定位服务变得普遍，该服务的最终用户的位置隐私将会显现出来。另一方面，水下语义位置的表示模型仍采用传统的地面坐标和几何点，可以进一步采用水下语义位置的概念来提高位置的私密性。在本文中，我们将讨论这两个位置隐私问题。本文从usasn定位服务用户的角度，讨论了与位置隐私相关的问题，提出了一种usasn节点协作方法，以防止攻击者在拦截通信或入侵中心节点时获取用户的精确位置。然后设计了“语义信封”的概念对位置信息进行封装，进一步增强了位置信息的保密性。
UASN has gained much attention during the past decades. Based on fruitful research and development, UASN could be a compelling component of the global IoT in the future. From the view of location privacy preservation, state-of-the-art investigations mainly concentrate on UASN infrastructures and focus on the location privacy preserving of the source location privacy of the infrastructures, such as anchor nodes, positioning nodes, and communication channel security. However, in the IoT scenario, the underwater positioning service provided by UASN becomes pervasive, and the location privacy of the end-user of this service will come into sight. On the other hand, the presentation model of underwater semantic location is still in use of traditional terrestrial coordinates and geometric points, the concept of underwater semantic location could be further adopted to improve the location privacy. In this article, both these two location privacy issues are concerned. From the view of a UASN positioning service user, we discuss location privacy-related problems and propos a UASN nodes collaboration method to prevent the adversary from learning the precise location of the user when they intercept the communication or hack the central node. Then a concept of "semantic envelope" is designed to encapsulate the location information, which could further strengthen the location privacy.
