A networking method, microchip, and device are described in which a first security engine may be associated with a chaining port and configured to perform an inner processing for an inner layer of encryption for a frame of data, while a second security engine may be associated with an external port and configured to perform an outer processing for an outer layer of encryption for the frame of data. Control logic may be configured to instruct the first security engine to execute both a transmit operation and a receive operation of the frame of data in association with the inner processing.
