Abstract:
Systems and methods are provided for quantum-resistant secure key distribution between a peer and an EAP authenticator by using an authentication server. The systems and methods include receiving requests for a COMMON-SEED and a quantum-safe public key from a peer and an EAP authenticator. The COMMON-SEED is encrypted using the quantum-safe public key of the peer and the quantum-safe public key of the EAP authenticator, and the encrypted COMMON-SEED is sent to the peer along with a request for a PPK ID from the peer to complete authentication of the peer. The PPK ID is received from the peer, and the encrypted COMMON-SEED and PPK ID is sent to the EAP authenticator. A quantum-resistant secure channel is established between the peer and the EAP authenticator when the peer and the EAP authenticator share the same COMMON-SEED and the same PPK-ID.
