Patent ID: 11909872
Assignee: CISCO TECHNOLOGY, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A system comprising:
one or more processors;
a non-transitory computer readable medium comprising instructions stored therein, the instructions, when executed by the one or more processors, cause the processors perform operations comprising:
receiving requests for a COMMON-SEED and a quantum-safe public key from a peer and an extendible authentication protocol (EAP) authenticator;
encrypting the COMMON-SEED using the quantum-safe public key of the peer and the quantum-safe public key of the EAP authenticator;
sending the encrypted COMMON-SEED to the peer along with a request for a Postquantum Preshared Keys ID (PPKID) from the peer to complete authentication of the peer;
receiving the PPK_ID from the peer, wherein the PPK ID is from a key pair obtained from a first Synchronizing Key Server (SKS) server in electrical communication with the peer based upon the encrypted COMMON-SEED;
sending the encrypted COMMON-SEED and PPK_ID to the EAP authenticator;
and establishing a quantum-resistant secure channel between the peer and the EAP authenticator, wherein a message of EAP success is delivered from the EAP authenticator to the peer when the peer and the EAP authenticator share the same COMMON-SEED and the same PPK-ID.
