Abstract
A network includes a first wireless node that communicates over a wireless network connection. The first wireless node includes a first encryption engine that processes a first initialization data set and a current transmit sequence associated with a current communication to generate a next transmit sequence that is employed to communicate with a second wireless node that derives a next received sequence that corresponds to the next transmit sequence to process a subsequent communication.
