The next generation wireless networks, dubbed 5G, provide higher bandwidth, lower latency, and better connectivity, supporting billions of interconnected communicating nodes, ranging from devices of a user, to sensors and autonomous machines. Three main enablers of the next generation wireless services are the heterogeneous (multi-tier) networks known as HetNet, millimetre wave (mmWave) radio spectrum, and massive multiple-input multiple-output (MIMO) antennas at mmWave. Providing security and trust in this environment while crucial, is particularly challenging because of the ability of malicious nodes to present fake identities, and eavesdrop, manipulate and jam the communication. The primary security challenges facing a node in a 5G system are: (i) identifying trustable nodes to connect to and, (ii) ensuring confidentiality and reliability of communication, and secure access to services. Physical layer properties of wireless systems provide a rich set of resources for system designers to enhance security and privacy of communication at affordable cost, complementing cryptographic security that are provided at the higher layer of communication stack. The goal of this project is to use the location-related information of the node for enhancing secure access.

被称为 5G 的下一代无线网络提供更高的带宽、更低的延迟和更好的连接性，支持数十亿个互连通信节点，从用户设备到传感器和自主机器。下一代无线服务的三个主要推动因素是被称为 HetNet 的异构（多层）网络、毫米波 (mmWave) 无线电频谱以及毫米波的大规模多输入多输出 (MIMO) 天线。在这种环境中提供安全和信任虽然至关重要，但特别具有挑战性，因为恶意节点能够提供虚假身份，并窃听、操纵和干扰通信。 5G 系统中的节点面临的主要安全挑战是：(i) 识别要连接的可信节点，(ii) 确保通信的机密性和可靠性以及对服务的安全访问。无线系统的物理层属性为系统设计人员提供了丰富的资源，以可承受的成本增强通信的安全性和隐私性，补充了通信堆栈高层提供的加密安全性。该项目的目标是利用节点的位置相关信息来增强安全访问。
