Abstract
Implementations provide for extending an authentication protocol to dynamically create a per user end to end encryption over a multi-hop path for data traffic, which provides an automatic triggering of authentication on each hop of a path when a client joins the network. A device includes a processor that is configured to, in response to receipt of a request for authentication from an end device, perform an authentication protocol to authenticate with an authentication server via an authenticator device. When the authentication protocol is successfully performed, the processor is configured to receive a message indicating that the device was successfully authenticated by the authentication server. The processor is configured to create a pairwise master key (PMK) from the parameters, and derive a pairwise temporary key (PTK) from a key derivation function seeded by the PMK. The processor is configured to encrypt, using the PTK, a message from the end device.
