Location-aware Secutiry and Privacy in 5G Wireless Networks

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，支持数十亿个相互连接的通信节点，从用户的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称为HetNet的异类(多层)网络、毫米波(毫米波)无线电频谱和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，但尤其具有挑战性，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，以及安全地访问服务。无线系统的物理层属性为系统设计者提供了一组丰富的资源，以便以负担得起的成本增强通信的安全性和私密性，补充了在通信堆栈的较高层提供的密码安全性。本项目的目标是利用节点的位置相关信息来增强安全访问。

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.
