  • QUANTUM CRYPTOGRAPHY IN AN INTERNET KEY EXCHANGE PROCEDURE
    Publication number: 20230412371
    Abstract: In some implementations, a first network device may communicate, with a second network device, one or more internet key exchange (IKE) messages to exchange a first identifier associated with the first network device and a second identifier associated with the second network device, and to indicate that a post-quantum preshared key (PPK) is to be used as a shared key for an IKE security association (SA) between the first network device and the second network device. The first network device may obtain, from a key management entity (KME), a quantum key based on providing the second identifier to the KME, wherein the PPK is based on the quantum key. The first network device may communicate, with the second network device, one or more IKE authentication messages to exchange a third identifier associated with the quantum key and to confirm that the second network device successfully obtained the PPK.
