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.

Abstract: A method is provided for quantum-resistant secure key distribution between a peer and an extendible authentication protocol (EAP) authenticator by using an authentication server. The method may include receiving requests for a COMMON-SEED and a McEliece public key from a peer and an EAP authenticator by an authentication server using an EAP method, encrypting the COMMON-SEED using the McEliece public key of the peer and the McEliece public key of the EAP authenticator by the authentication server, and sending the encrypted COMMON-SEED from the authentication server to the peer along with a request for a PPK_ID from the peer using the EAP method to complete authentication of the peer. The method may also include receiving the PPK_ID from the peer using the EAP method, where the PPK_ID is from a key pair consisting of PPK_ID and PPK obtained from a first SKS server in electrical communication with the peer based upon the encrypted COMMON-SEED.

Abstract: Presented herein are methodologies for establishing secure communications in a post-quantum computer context. The methodology includes receiving, from a first communications device, at a second communications device, a secret seed value, or otherwise obtaining the secret seed value; initializing a session key service with the secret seed value; receiving, from the first communications device, at the second communications device, a pre-shared key identifier; querying the session key service for a pre-shared key corresponding the pre-shared key identifier; receiving, from the session key service, the pre-shared key; deriving a session key based, at least in part, on the pre-shared key; receiving from the first communications device, at the second communications device, data encrypted with the session key; and decrypting the data at the second communications device using the session key.

Abstract: A method is described and in one embodiment includes identifying at an initiator element a list of Internet protocol (“IP”) prefixes corresponding to routes designated as interesting routes, wherein the IP prefixes are included in a Routing Information Base (“RIB”) of the initiator; monitoring the RIB for a change in the list of IP prefixes; and, responsive to detection of a change in the list of IP prefixes, injecting at least a portion of the changed list of IP prefixes into a payload of an IKEv2 NOTIFY message and sending the IKEv2 NOTIFY message to a responder element peered with the initiator element, wherein the responder element updates an RIB of the responder element using the IP prefixes included in the received IKEv2 NOTIFY message.
