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 "verifiable light weight monitoring for certificate transparency logs"):
  Abstract: Trust in publicly verifiable Certificate Transparency (CT) logs is reduced through cryptography, gossip, auditing, and monitoring. The role of a monitor is to observe each and every log entry, looking for suspicious certificates that interest the entity running the monitor. While anyone can run a monitor, it requires continuous operation and copies of the logs to be inspected. This has lead to the emergence of monitoring-as-a-service: a trusted party runs the monitor and provides registered subjects with selective certificate notifications, e.g., "notify me of all foo.com certificates". We present a CT/bis extension for verifiable light-weight monitoring that enables subjects to verify the correctness of such notifications, reducing the trust that is placed in these monitors. Our extension supports verifiable monitoring of wild-card domains and piggybacks on CT's existing gossip-audit security model.
