How to Encrypt the USB Connection

To secure the USB connections, encrypt the entire data transfer (user data, control data and protocol data) be-
tween the clients and the USB devices connected to the UTN server.
The protocols SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are used for encryption.
The encryption strength is defined via the encryption protocol and level  64.
WARNING
The SEH UTN Manager does not support the encryption level Low. If you set up
Low in combination with an encrypted USB connection, a connection cannot be
established.
Use an encryption level as high as possible.
If connections are encrypted, client and UTN server communicate over the encrypted UTN port. By default, that
is port 9443. If the port is already in use on your network, e.g. for another application, you can change the port
number  55.
