human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "mice and covert channels"):
  Abstract: Any secure network is only as secure as its weakest component. With overt channels tightly secured and attackers have started focusing on optical, audible, magnetic, and thermal covert channels to access sensitive systems. In this paper, we present a novel, reliable and bidirectional optical covert channel which uses optical mice. In this channel, the photocell in the mouse is used as a receiver while the LED is used as a transmitter. Our multiple experiments, which use mouse to mouse, mouse to camera and torch to mouse, show that the transmission rate can go as high as 10 bits per second. Additionally, we study the effects of infrared, distance and brightness on mouse input. We also show that infrared mice are susceptible to a similar kind of attack.
