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 "when a patch is not enough hardfails software exploitable hardware bugs"):
  Abstract: Modern computer systems are becoming faster,#R##N#more efficient, and increasingly interconnected with each generation. Consequently, these platforms also grow more complex,#R##N#with continuously new features introducing the possibility of new#R##N#bugs. Hence, the semiconductor industry employs a combination#R##N#of different verification techniques to ensure the security of#R##N#System-on-Chip (SoC) designs during the development life cycle.#R##N#However, a growing number of increasingly sophisticated attacks#R##N#are starting to leverage cross-layer bugs by exploiting subtle interactions between hardware and software, as recently demonstrated#R##N#through a series of real-world exploits with significant security#R##N#impact that affected all major hardware vendors.
