Hello Mr Peter,

Thank you for your reply. It was my first attempt to develop a protocol.
Hence, the mistake. I hope to do better work next time.

Although PUF is not my idea, I would like to know if it is a good idea. I
thought it was the future of IoT world. Should we invest time, money and
energy in it ? Please advise.

Thanks and Regards,
Sankalp Bagaria.
