Application: Method in a telecommunication network, and computer system (Patent ID: US20240056824A1)

The patent filed by Telefonaktiebolaget LM Ericsson describes a method for secure exchange of quantum keys in a telecommunication network to enable encryption of sensitive data within messages exchanged by lawful interception (LI) entities. The method involves an LI administrative function obtaining a quantum key and a key stream identifier (KSID) from a quantum key distribution network (QKDN), transmitting the KSID to an LI entity, and the LI entity obtaining the quantum key associated with the KSID from the QKDN. This process ensures a secure exchange of quantum keys for encryption purposes.

The method further includes interactions between the LI administrative function and the LI entity, such as transmitting queries to determine the LI entity's capability of obtaining a quantum key from the QKDN and responding accordingly. The communication between the LI administrative function and the LI entity is facilitated through specific interfaces as per standards set by the European Telecommunications Standards Institute (ETSI). Additionally, the patent also covers a computer system configured to perform the method described, ensuring the secure exchange of quantum keys within the telecommunication network for encryption purposes, particularly in the context of lawful interception activities.
