Abstract
Systems and methods may include sending, to a network registrar, an extended duplicate address request (EDAR) message including a first nonce generated by a host computing device, and receiving, from the network registrar, an extended duplicate address confirmation (EDAC) message including a second nonce, the second nonce being signed by the network registrar via a private key of a first public key infrastructure (PM) key pair of the network registrar via a first signature. The method further includes sending a first neighbor advertisement (NA) message to the host computing device including the second nonce. The second nonce and the private key of the network registrar verifies the first signature from the network registrar, the verification of the first signature indicating that the router is not impersonating the network.
