Through direct communication, device-to-device (D2D) technology can increase the overall throughput, enhance the coverage, and reduce the power consumption of cellular communications. Security will be of paramount importance in 5G, because 5G devices will directly affect our safety, such as by steering self-driving vehicles and controlling health care applications. 5G will be supporting millions of existing devices without adequate built-in security, as well as new devices whose extreme computing power will make them attractive targets for hackers.This paper presents a survey of the literature on security problems relating to D2D communications in mobile 5G networks. Issues include eavesdropping, jamming, primary user emulation attack, and injecting attack. Because multipath routing emerges as a strategy that can help combat many security problems, particularly eavesdropping, the paper contains an extensive discussion of the security implications of multipath routing. Finally, the paper describes results of a simulation that tests three path selection techniques inspired by the literature. The simulation reveals that routing information through interference disjoint paths most effectively inhibits eavesdropping.

5G设备到设备的通信安全性和多路径路由解决方案

通过直接通信，设备到设备（D2D）技术可以提高总体吞吐量，增强覆盖范围并降低蜂窝通信的功耗。安全性在5G中至关重要，因为5G设备将直接影响我们的安全性，例如通过驾驶自动驾驶汽车和控制医疗保健应用程序。5G将为数百万个没有足够内置安全性的现有设备提供支持，以及其强大的计算能力使其成为黑客有吸引力的目标的新设备。本文提供了有关移动5G中与D2D通信相关的安全性问题的文献调查。网络。问题包括窃听，干扰，主要用户仿真攻击和注入攻击。由于多路径路由是一种可以帮助解决许多安全问题的策略，特别是在进行窃听时，本文包含了有关多路径路由的安全性的广泛讨论。最后，本文描述了模拟的结果，该模拟测试了受文献启发的三种路径选择技术。仿真表明，通过不相干的干扰路径路由信息最有效地抑制了窃听。
