Wireless access is an essential to the networks that underpin modern life, providing communications for people, vehicles, machines, infrastructure, and the wide variety of devices that will make up the Internet of Things (IoT). They will become increasingly important to support safe transportation and future healthcare. Society is increasingly vulnerable to network cyber attack, for motivations ranging from financial extortion through terrorist disruption to subversion. Cyber attacks can be mounted remotely through networks, making them attractive to malefactors who can operate safely and anonymously from anywhere in the world. Cyber defence and associated research has become critical, mainly directed at developing and rolling out technical encryption and authentication measures in the network protocols and embedding the essential processes in organisations. Nevertheless exploits continue as attackers discover new vulnerabilities that were not considered in the system design or arise through imperfect implementations. Fixing these requires updating both functionality and credentials of the network elements as threats emerge.By contrast cyber-attack via the wireless interface, exploiting vulnerabilities in the physical layer and lower layers of the protocol stack, has received much less attention. As network originated exploits become more difficult it can be expected that more attacks will be mounted through the "air interface". The means to develop and mount such attacks are increasingly available with the proliferation of low cost software-defined radio (SDR) platforms and open-source software, and the ubiquity of potentially hackable wireless terminals. More research on this problem is needed to find solutions to be retrospectively applied to existing systems, influence the next generation of wireless standards, raise awareness of the potential problems, and train engineers to develop and embed defensive capability in radio standards and products. Crucial will be the ability to change the physical layer functionality, right to the antenna, by changing system software. This is not possible with current equipment or indeed envisaged in the 5G. Apart from countering the security threat, such technology will be needed to enable the future adoption of Dynamic Spectrum Access (DSA), in which, rather than frequency bands being administratively licensed to specific users, spectrum will be allocated dynamically according to evolving demand in space and time.The project partners, Toshiba Research, Roke, University of Bristol, and GCHQ, share a vision of Secure Wireless Agile Networks (SWAN) to be developed in this research partnership. The project scope will include technical deliverables; the shaping of policy and standards; and the training and career development of the SWAN teams. The co-created 5-year programme will integrate academic and industrial teams in activities that address the following Research Challenges (RCs).1. Threat Synthesis & Assessment: how can RF interfaces be attacked, beyond the threats envisaged in their design?2. RF Cyber Detection & Defence: techniques to detect RF cyber attack and mitigate their effects.3. Cyber Secure Radio Design: designing radios whose RF characteristics can be updated in the field to deal with new threats, which also enable DSA. 4. Secure Dynamic Spectrum Access: enabling technology for securely sharing spectrum for most efficient usage.The consequences of not addressing the above will potentially make the wireless channel an Open Attack Surface for cyber attack. SWAN's technological solutions will place the UK at the forefront of enabling the fundamental parameters and architectures of wireless systems to be adaptable to new spectrum and interface specifications; resilient to accidental or induced failures (such as jamming); and resistant to cyber-attack.

无线接入对于支撑现代生活的网络至关重要，它为人、车辆、机器、基础设施以及将构成物联网(IoT)的各种设备提供通信。它们在支持安全交通和未来的医疗保健方面将变得越来越重要。社会越来越容易受到网络网络攻击，动机从金融勒索到恐怖分子破坏再到颠覆。网络攻击可以通过网络远程发动，这使得它们对能够在世界任何地方安全和匿名操作的不法分子具有吸引力。网络防御和相关研究已变得至关重要，主要针对开发和推出网络协议中的技术加密和认证措施，并将必要的流程嵌入组织中。然而，随着攻击者发现系统设计中没有考虑到的新漏洞或由于不完善的实现而出现的新漏洞，利用漏洞仍在继续。解决这些问题需要在出现威胁时更新网络元素的功能和凭据。相比之下，通过无线接口进行的网络攻击利用协议栈物理层和较低层的漏洞，受到的关注要少得多。随着网络发起的攻击变得更加困难，可以预期会有更多的攻击通过“空中接口”发起。随着低成本软件定义无线电(SDR)平台和开源软件的激增，以及可能被黑客攻击的无线终端的无处不在，开发和发动此类攻击的手段越来越可用。需要对这一问题进行更多的研究，以找到可追溯应用于现有系统的解决方案，影响下一代无线标准，提高对潜在问题的认识，并培训工程师在无线电标准和产品中开发和嵌入防御能力。关键是能够通过更改系统软件来更改物理层功能，甚至是天线。这在目前的设备上是不可能的，实际上在5G中也是不可能的。除了应对安全威胁外，还需要这种技术来支持未来采用动态频谱接入(DSA)，在DSA中，频谱将根据空间和时间上不断变化的需求进行动态分配，而不是将频段行政许可给特定用户。项目合作伙伴，东芝研究、Roke、布里斯托尔大学和GCHQ，分享了在此研究伙伴关系中开发的安全无线敏捷网络(SWAN)的愿景。项目范围将包括技术成果；政策和标准的制定；以及天鹅队的培训和职业发展。共同创建的为期5年的方案将把学术和工业团队纳入应对以下研究挑战(RCS)的活动中。威胁综合与评估：如何攻击射频接口，超出其设计设想的威胁？2.射频网络检测与防御：检测射频网络攻击并减轻其影响的技术。网络安全无线电设计：设计射频特性可在现场更新以应对新威胁的无线电，这也支持DSA。4.安全动态频谱访问：启用安全共享频谱以实现最有效使用的技术。不解决上述问题的后果可能会使无线通道成为网络攻击的开放攻击面。SWAN的技术解决方案将使英国处于使无线系统的基本参数和架构能够适应新的频谱和接口规范、对意外或诱发故障(如干扰)具有弹性以及抵御网络攻击方面的领先地位。
