使用梯度上升方法保护5G及更高无线系统中的V2I通信

Securing V2I Communications in 5G and Beyond Wireless System Using Gradient Ascent Approach

Neji Mensi, Danda B. Rawat, Elyes Balti

摘要:

5G及以后的无线系统,而不仅仅是4G的扩展,被视为“网络的网络”,预计将集成包括无线车载网络(WVN)在内的异构无线网络。WVN承诺解决许多问题,例如减少道路事故,交通堵塞,燃料消耗和通勤时间,这受到各种安全问题的影响,例如窃听,攻击者试图被动地偷听秘密传输的信号(这使得检测/防御非常困难)。在这项工作中,我们的目标是实现一个安全方案,通过提高在Sub-6 GHz和毫米波(mmWave)频段的保密能力。用于5G及更高无线网络的车对基础设施(V2 I)。与以往的作品中的保密容量增加随机增加的源功率或设置系统组合器/预编码器,在这项工作中,我们采用梯度上升算法搜索最佳的组合器/预编码器,最大限度地提高保密率的性能。我们进一步提出了两种不同的优化方案:固定和可变的传输功率。

英文摘要:

The 5G and beyond wireless systems, instead of being just an extension of 4G, are regarded as `network of networks' which is expected to integrate heterogeneous wireless networks including wireless vehicular networks (WVN). The WVN promises to solve many issues such as reducing road accidents, traffic jams, fuel consumption and commute time, which is subject to various security issues such as eavesdropping, where attackers attempt to overhear the secret transmitted signal passively (which makes the detection/defense very difficult). In this work, our objective is to implement a security scheme by improving the secrecy capacity in Sub-6 GHz and millimeter-wave (mmWave) bands. Vehicle-to-Infrastructure (V2I) for 5G and beyond wireless network. Unlike previous works where the secrecy capacity is increased by randomly augmenting the source power or setting the system combiners/precoders, in this work we employ the Gradient Ascent algorithm to search for the best combiners/precoders that maximize the secrecy rate performance. We further present two different optimization scenarios: fixed and variable transmission power.
