Systems, methods, and other embodiments associated with processing secure network traffic are described. One example method includes determining whether a device is a preconfigured member of a group key system. If the device is not a preconfigured member then the method selectively establishes membership in the group key system by requesting membership from a group controller. The example method may also include receiving a set of keys from the group controller and being assigned a role by the group controller. The method may further include processing secure network traffic as an inspection point, a rewriting point, and/or a validation point based on the received set of keys and the assigned role(s).

According to an approach for assigning network addresses to network devices, an authentication request that requests authentication of identification data that uniquely identifies a network device is generated and sent to an authentication mechanism. An authentication response is received from the authentication mechanism that indicates whether the network device is authorized to access a first network. If the authentication response indicates that the network device is authorized to access the first network, then a first network address on a first network is assigned to the network device. If the authentication response indicates that the network device is not authorized to access the first network, then a second network address on a second network to the network device is assigned. If no authentication response is received from the authentication mechanism, then the second network address on the second network is assigned to the network device.
