Cover simply instructs a Bento box to ensure that a given circuit always transmits at a fixed rate, sending junk traffic if it has no legitimate traffic to send. To see the strength of this simple primitive, consider how it could compose with Browser: a client could establish bidi- rectional cover traffic with an exit node, then initiate the download of a webpage. Instead of waiting until the web- page is fully downloaded to begin sending it, the Bento box could send back immediately, permitting support for inter- active webpages without sacrificing anonymity.
