Abstract
A lawful interception administrative function, LI ADMF, () in a telecommunication network () obtains from a quantum key distribution network, QKDN, () a quantum key and a key stream identifier, KSID, associated with the quantum key. The LI ADMF () transmits the KSID associated with the quantum key to an LI entity () in the telecommunication network (). The LI entity () then obtains, from the QKDN (), a quantum key associated with the KSID transmitted by the LI ADMF (). Such a procedure provides a secure exchange of quantum keys to enable encryption of sensitive data within messages exchanged by LI entities in the telecommunication network ().
