| 发明名称 | Quantum key distribution involving moveable key device | ||
| 摘要 | A method of key distribution from a first entity to a second entity including the first entity communicating with a moveable key device so as to share a secret data with said moveable key device, relocating said moveable key device to a location having a quantum link with said second entity, transmitting a quantum signal from said moveable key device to said second entity on said quantum link, the quantum signal being based on said secret data; and said first entity and said second entity undertaking key agreement based on the quantum signal received by the second entity. Such a method allows the principles of quantum key distribution to be applied even in the absence of a suitable quantum communications link between the first and second entities. | ||

| 主权项 | 1. A method of key distribution from a first entity to a second entity comprising the steps of: the first entity communicating with a moveable key device so as to share a secret data with said moveable key device, relocating said moveable key device to a location having a quantum link with said second entity, transmitting a quantum signal from said moveable key device to said second entity on said quantum link, the quantum signal being based on said secret data; and said first entity and said second entity undertaking key agreement based on the quantum signal received by the second entity. | ||
