A chain of trust is designed to allow multiple users to create and use software on the system, which would be more difficult if all the keys were stored directly in hardware. It starts with warnings from the MAP Gateway UI when you attempt to use it without the software being digitally signed. The signing authority only signs boot programs that enforce security, such as running only programs that are themselves signed, or allowing only signed code to have access to certain features of the machine. This process may continue for several layers.
