项目摘要

Security and privacy have become a paramount concern in modern ICT, as threats from cybercrime are soaring. This year's global economic crime survey conducted by PwC reported that cybercrime has jumped from 4th to 2nd place among the most-reported types of economic crime. The severity of threat on the business, financial, infrastructure and other UK sectors makes all facets of security and risk management pertinent, and their importance cannot be overstated. Physical layer security (PS) provides an extra layer of security on top of the traditional cryptographic measures. It obstructs access to the wireless traffic itself, thus averting any higher layer attack. Encompassing a number of key technologies spanning secure beamforming, artificial noise design, network coding, cooperative jamming, graph theory, and directional modulation, PS is now commonly accepted as one of the most effective forms of security. While appealing as a theoretical concept, PS still faces a number of critical challenges that prevent it from wide commercial adoption in 5G and beyond, involving the lack of secure 5G signalling, the provision of eavesdroppers' information, and the applicability of existing theoretical techniques in real environments and under low-specification hardware.CI-PHY addresses the abovementioned challenges, and promotes a paradigm shift on security by exploiting interference. In particular, CI-PHY exploits constructive interference for Physical Layer Security by:- Specifically tailored fundamental waveform design to exploit interference, that provides a low complexity solution with limited hardware requirements;- Artificial noise and jamming to actively improve the desired receivers' SNR under secrecy constraints, and further improve secrecy by designing the artificial noise to align destructively to the signal at the eavesdropper;- Robust approaches for real implementation by taking hardware impairments into account to reduce the hardware requirements for providing secrecy with resource-constrained devices;- Real implementation and over-the-air testing of security solutions to evaluate and optimise performance in commercially relevant environments.CI-PHY will be performed with the Interdisciplinary Centre for Security, Reliability and Trust in University of Luxembourg, and industrial partners QinetiQ, BT, National Instruments and Huawei, and aspires to kick-start an innovative ecosystem for high-impact players among the infrastructure and service providers of ICT to develop and commercialize a new generation of secure and power-efficient communication networks, and address the unprecedented vulnerability of emerging ICT services to cyber threats.

随着网络犯罪威胁的激增，安全和隐私已成为现代信通技术的首要关切。普华永道今年进行的全球经济犯罪调查报告显示，网络犯罪在报告最多的经济犯罪类型中从第四位跃升至第二位。商业、金融、基础设施和其他英国部门面临的威胁的严重性使得安全和风险管理的各个方面都变得相关，其重要性怎么强调都不为过。物理层安全（PS）在传统加密措施之上提供了额外的安全层。它阻碍了对无线流量本身的访问，从而避免了任何更高层的攻击。PS包含了许多关键技术，包括安全波束形成，人工噪声设计，网络编码，合作干扰，图论和定向调制，现在被普遍认为是最有效的安全形式之一。虽然作为一个理论概念很有吸引力，但PS仍然面临许多关键挑战，这些挑战阻止了它在5G及以后的广泛商业应用，涉及缺乏安全的5G信令、提供窃听者的信息以及现有理论技术在真实的环境中和低规格硬件下的适用性。并通过利用干涉促进安全范式的转变。具体地，CI-PHY通过以下方式利用相长干扰来实现物理层安全性：-专门定制的基本波形设计以利用干扰，其提供具有有限硬件要求的低复杂度解决方案;-人工噪声和干扰以在保密约束下主动地提高期望接收机的SNR，并且通过设计人工噪声以破坏性地对准窃听者处的信号来进一步提高保密性;- 通过考虑硬件损伤以减少用于为资源受限的设备提供保密的硬件要求，用于真实的实现的鲁棒方法;- 安全解决方案的真实的实施和空中测试，以评估和优化商业相关环境中的性能。CI-PHY将与卢森堡的安全、可靠性和信任跨学科中心以及工业合作伙伴QinetiQ、BT、National Instruments和华为一起进行，并渴望为ICT基础设施和服务提供商中的高影响力参与者启动一个创新生态系统，以开发和商业化新一代安全和电力我们的目标是建立高效的通信网络，并解决新兴ICT服务对网络威胁的前所未有的脆弱性。
