    A team of University of Maryland Institute for Advanced Computer Studies (UMIACS) researchers developed “provable avoidance routing” that they call Alibi Routing; it’s an overlay routing protocol that provides Internet users with a method to avoid sending their data through countries known for their censorship. Users specify where they want their packets NOT to go and Alibi Routing can provide “concrete proof” that users’ data did not pass through “undesired geographic regions.”

    The researchers unveiled Alibi Routing at the 2015 Association for Computing Machinery Special Interest Group on Data Communication (ACM SIGCOMM) conference. The research paper (pdf) “introduces a primitive, provable avoidance routing that, when given a destination and region to avoid, provides ‘proof’ after the fact that a packet and its response did not traverse the forbidden region. We rely on the insight that a packet could provide an ‘alibi’—a place and time where it was—to prove that it must have avoided the forbidden region in transit from source to destination.”
