  • Patent number: 12640919
    Abstract: A network device may determine that a particular security association (SA) is to be established with a peer network device and that a post-quantum preshared key (PPK) cannot be obtained by the network device. The network device may determine that establishment of quantum-secure SAs is not mandatory for the network device. The network device may generate based on determining that the PPK cannot be obtained by the network device, and based on determining that establishment of quantum-secure SAs is not mandatory for the network device, a pseudo-PPK, and may generate, using the pseudo-PPK, pseudo-PPK authentication information associated with the network device. The network device may generate, using a non-quantum-secure key, non-quantum-secure authentication information associated with the network device.

  • Patent number: 12250302
    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.

  • Patent number: 12052223
    Abstract: A network device identifies an Internet Protocol Security (IPsec) tunnel that connects the network device to a remote device and determines that dead peer detection (DPD) is enabled at the network device. The network device receives a first DPD request message from the remote device via the IPsec tunnel, and sends a first DPD response message to the remote device via the IPsec tunnel. The network device determines that a workload of the network device satisfies a threshold amount, and sends one or more encapsulating security payload (ESP) packets that include traffic flow confidentiality (TFC) payload data to the remote device via the IPsec tunnel. The network device determines that the workload of the network device does not satisfy the threshold amount. The network device receives a second DPD request message from the remote device and sends a second DPD response message to the remote device via the IPsec tunnel.

  • Patent number: 11405422
    Abstract: A network device may receive, from a transmitting network device, a packet, wherein the packet includes a first outer internet protocol (IP) header, a Generic Routing Encapsulation (GRE) header, a second outer IP header, an Encapsulating Security Payload (ESP) header, and an inner packet, wherein the inner packet is encapsulated by the ESP header, the ESP header is encapsulated by the second outer IP header, the second outer IP header is encapsulated by the GRE header, and the GRE header is encapsulated by the first outer IP header. The network device may decapsulate the packet to remove the first outer IP header and the GRE header from the packet. The network device may decrypt, after decapsulating the packet, the packet to identify the inner packet. The network device may cause one or more actions associated with the inner packet to be performed.
