Abstract
A quantum key distribution, QKD, method, applied to a QKD end-node by locally generating a local key, and dividing the local key into a first local key part and a second local key part, receiving, via a ground-based first path, remote key information including an encrypted remote key generated by a remote, further QKD end-node. In addition, the method includes receiving, via a satellite-based second path, a first remote key part of the remote key and performing decryption on the remote key information using the first remote key part to obtain a second remote key part of the remote key. The method further comprises combining the second remote key part and the second local key part with each other to obtain a secret key. Also an end-node configured to perform such a method and a network with such an end-node.
