Worth Reading: The Internet and Trust

This narrative refers to the understanding that trust mitigates the basic uncertainties that the Internet architecture has imposed upon its operators since its inception. To this day, network engineers cannot generally be certain about the validity of the routing announcements that they receive from interconnected networks, and they have little insight into the legitimacy of the traffic that they are mandated to transmit. Historically, network operators knew and trusted one another, and, as a result, the Internet worked in spite of its uncertainties. —APNIC
