Abstract
An apparatus including a key mixing circuit, an input circuit, a packet number circuit, and an encryption circuit. The key mixing circuit generates a plurality of encryption seeds, wherein each encryption seed is generated based upon a predetermined key, a transmitter address, and a corresponding value for a packet number. The input circuit receives a plurality of packets of data. The packet number circuit inserts, into each packet of data received by the input circuit, a different one of the corresponding values for a packet number. The encryption circuit encrypts each packet of data using the encryption seed that was generated based on the corresponding value for the packet number inserted into the packet of data. The key mixing circuit generates each of the plurality of encryption seeds prior to the input circuit receiving the plurality of packets of data.
