CONCLUSION<br />

This KEELOQ/<strong>AES</strong> transmitter firmware has all the<br />

features of a standard hardware encoder. What makes<br />

this firmware implementation useful to the designer is<br />

that it gives the designer the power and flexibility of<br />

modifying the encoding and/or transmission formats<br />

and parameters to suit their security system.<br />
