To increase the security, the communication between the device and provisioning server can be done via the HTTPS protocol.
When using HTTPS, the communication is encrypted, this means that the data can not be read by others.
To use HTTPS, you only need to change the provisioning URL to example:
Normal: http://profile.gigaset.net/device
Secure: https://profile.gigaset.net/device
The N720 needs an additional reboot after loading the certificate, this will be changed.
