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 "a multilevel cybersecurity and safety monitor for embedded cyber physical systems"):
  Abstract: Cyber-physical systems (CPS) are composed of various embedded subsystems and require specialized software, firmware, and hardware to coordinate with the rest of the system. These multiple levels of integration expose attack surfaces which can be susceptible to attack vectors that require novel architectural methods to effectively secure against. We present a multilevel hierarchical monitor architecture cybersecurity approach applied to a flight control system. However, the principles present in this paper apply to any CPS. Additionally, the real-time nature of these monitors allow for adaptable security, meaning that they mitigate against possible classes of attacks online. This results in an appealing bolt-on solution that is independent of different system designs. Consequently, employing such monitors leads to strengthened system resiliency and dependability of safety-critical CPS.
