Abstract
A first key management entity (KME) in a mobile edge network engages in quantum key distribution (QKD) with a second KME in a far network to generate a secret cryptographic key that is shared between the first KME and the second KME. The first KME determines a key identifier (ID) for associating with the cryptographic key, and sends the key ID to the second KME for association with the secret cryptographic key at the second KME. The first KME receives a session request from a first session endpoint for a session across at least one of the mobile edge network or the far network. The first KME sends the key ID and the cryptographic key to the first session endpoint for establishing an encrypted session across the at least one of the mobile edge network or the far network.
