Very soon, trillions of wireless gadgets will be linked to billions of people, resulting in an overloaded spectrum. Device-to-device (D2D) wireless communication offers a new paradigm for addressing these impending issues by permitting the transmission of data between proximity devices. However, if the D2D communication system is not secured, the quality-of-service may be disrupted by a variety of security assaults. Furthermore, the system will become unreliable, posing a hurdle to D2D’s expansion. In this work, we look into the security features of D2D communication, which are crucial for its widespread adoption. This article provides an in-depth review of the conventional security features of D2D communication, as well as associated issues. This work identifies the possible solutions to be carried out and the future directions from existing research work by analyzing security architecture, security threats, existing algorithms, open security challenges, and limitations. The fundamental goal of this effort is to help related researchers to understand D2D security and privacy concerns in a nutshell.

很快，数以万亿计的无线设备将连接到数十亿人，导致频谱过载。设备到设备 (D2D) 无线通信通过允许在邻近设备之间传输数据，为解决这些迫在眉睫的问题提供了新的范例。但是，如果 D2D 通信系统不安全，则服务质量可能会受到各种安全攻击的影响。此外，系统将变得不可靠，对 D2D 的扩展构成障碍。在这项工作中，我们研究了 D2D 通信的安全特性，这对其广泛采用至关重要。本文深入回顾了 D2D 通信的传统安全特性以及相关问题。这项工作通过分析安全架构、安全威胁、现有算法、开放式安全挑战和限制，确定了现有研究工作中可能实施的解决方案和未来方向。这项工作的基本目标是帮助相关研究人员简要了解 D2D 安全和隐私问题。
