METHOD IN A TELECOMMUNICATION NETWORK, AND COMPUTER SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240056824 titled 'METHOD IN A TELECOMMUNICATION NETWORK, AND COMPUTER SYSTEM

Simplified Explanation

The abstract describes a method for a lawful interception administrative function in a telecommunication network to obtain a quantum key and key stream identifier from a quantum key distribution network, transmit the key stream identifier to another entity in the network, and then obtain the quantum key associated with the key stream identifier from the quantum key distribution network.

• Lawful interception administrative function (LI ADMF) obtains quantum key and key stream identifier from quantum key distribution network (QKDN).
• LI ADMF transmits key stream identifier to another entity in the telecommunication network.
• The entity obtains the quantum key associated with the key stream identifier from the QKDN.
• Enables secure exchange of quantum keys for encryption of sensitive data in messages exchanged by entities in the telecommunication network.

Original Abstract Submitted

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 ().
