Even if it was possible I'm not sure an asymmetric key approach would bring as much benefit as it initially seems. If it were possible to keep the private key truly secret then one could obviously use the same public key with all devices without worrying that knowing it would allow an outside party to decode transmitted keys but I think there are still issue here - I discuss this in more detail <a href="http://depletionregion.blogspot.ch/2013/10/ideas-for-improving-smart-config.html" rel="nofollow">here</a>.

Obviously, using a public key in Smart Config App would eliminated such issues.Anonymoushttps://www.blogger.com/profile/00859525083060801801noreply@blogger.com
