Latest Patents
Krishna Priya Balakrishnan holds a patent for "Continuous authentication of peers in networks using post-quantum pre-shared keys." This patent describes techniques and architecture for reauthentication of two IPsec peers during a key refresh process. The peers can reauthenticate each other based on a shared secret, which is configured as a post-quantum pre-shared key (PPK). The patent outlines how PPKs are stirred during key derivation while refreshing session keys during IKEv2 and IPsec rekey. This process involves communicating the PPK-ID from a rekey initiator to a rekey responder by adding a PPK_ID payload in the rekey message exchange. This innovation enables stronger quantum-safe session keys when dynamic PPK is used or when the manual PPK is rotated frequently. The knowledge of the shared PPK is verified by having both peers exchange authentication payloads signed with a PPK, which includes an IKEv2 NOTIFY payload 'AUTH_PPK' to carry PPK-signed authentication data. This serves the purpose of frequent re-authentication of the peers as part of the key refreshes.
