Abstract
A network authentication system with dynamic key generation that facilitates the establishment of both endpoint identity, as well as a secure communication channel using a dynamically-generated key between two end devices (potentially on separate local area networks). An interactive or non-interactive authentication protocol is used to establish the identity of the target end device, and dynamic key generation is used to establish a shared symmetric session key for creating an encrypted communication channel between the end devices.
