I want to create an usb stick which contains an ubuntu installation that:

  • can be used as a working environment (Covered in: How do I install Ubuntu to a USB key?) - ie the ubuntu installation on the stick must provide an accessible home folder.
  • Is completely encrypted.

I intend to use it as a secure environment to work on sensitive customer data - and also need the system on the stick to be able to connect to the internet. How do I realize the complete usb stick encryption?

I am also very thankfull for any further articles and ideas on this topic!

You won't be able to encrypt the entire disk - and shouldn't need to. If you constrain all the sensitive data to just your home folder than you can select the "Encrypt home folder" option during the setup process. More on Encrypted home partitions can be found in this question
