A nozzle for use in a gas turbine engine includes a nozzle door having a first end, a second end opposed from the first end, and a pivot between the first end and the second end. The seed value is computed by subjecting variable data to a Secure Hashing Algorithm, and truncating the right most, or left most, 16 bytes from the message digest generated. Such surfacing films may be incorporated into composite structures, for example, by co-curing, as an outermost surface layer. In one embodiment, information relating to network traffic is monitored both by a first set of devices associated with source addresses for that network traffic and a second set of devices associated with destination addresses for that network traffic.
