<p>Question solved.<br>
As i understand every device(mobile or desktop) has own key pair. When pairing occures device receive remote public key and sends own. E.g. each device has public keys of EVERY devices paired with. <br>
When device send package it encrypt it with apropriate recipien public key. When device receive package it decrypt it with OWN private key.<br>
Right?</p>

Hmm this is not a bug. You store public key if device already have<br>
public key and provide it for desktop?<br>
I don't understand whole auth system :(<br>
