Q-DOS light: Quantum key distribution for Drones with Optimal Size, weight and power

在民用、政府和国防应用中，无人机和卫星等空中和太空平台的使用正变得司空见惯。在这些应用中，信息的安全是非常重要的。由于无线电频谱被过度分配，终端用户正在转向自由空间光通信以提高数据速率。Q-DOS light项目（用于无人机的量子密钥分配，具有最佳尺寸重量和功率）旨在通过为机载平台提供具有量子加密的紧凑型光通信系统来解决问题，以实现超安全数据传输。高速链路将利用量子密钥分发（QKD）传输加密消息，并通过窃听检测功能监视链路的拦截。该系统将在小型无人机（7公斤以下）上进行演示，并满足非常具有挑战性的尺寸、重量和功率（SWaP）限制。Q-DOS轻型合作伙伴代表了整个价值链，将为英国和全球工业提供独特的解决方案。

The use of air and space platforms such as drones and satellites is becoming routine in civil, government and defence applications. Security of information is of great importance in such applications. As the radio frequency spectrum isoverallocated, end users are turning to free-space optical communications for increased data rates. Project Q-DOS light (Quantum key distribution for Drones with Optimal Size weight and power) aims to solve the problem by delivering a compact optical communications system with quantum encryption for airborne platforms for hyper-secure data transfer. The high-speed link will utilise Quantum Key Distribution (QKD) to transmit encrypted messages, and monitor for interception of the link via an eavesdropping detection feature. The system will be demonstrated whilst being flown on a small drone (under 7kg) and meet very challenging Size, Weight and Power (SWaP) constraints. Q-DOS light partners represent the whole spectrum of the value chain that will deliver a unique solution to the UK and global industries.
