Below is a high-level description:A user specifies two things: who they want to communicate with (the destination), and arbitrary "forbidden" geographic regions they wish to avoid while doing so.

We call such a peer anHere's an example of a user in Italy trying to communicate with a server in Norway while avoiding Germany:The green regions denote where alibisexist.

The user gets proof that the alibi avoided the region, if it was able to do so.
