Abstract
A method is provided for processing a data packet on reception, where the data packet is transmitted by a first node to a second node over a link of a wireless electronic communications network. The packet includes a header and payload data. The method includes a step of receiving the data packet in two stages, a first stage of receiving the header and a second stage of receiving the payload data. The first stage includes the following steps performed by the second node on receiving a header of the data packet: detecting in the received preamble an authentication preamble for authenticating the link; using the data packet authentication preamble to authenticate the link; and in the event of the authentication having a positive result, deciding to trigger the second stage of receiving the payload data from the data packet.
