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 "on the equivalency of reliability and security metrics for wireline networks"):
  Abstract: In this paper, we show the equivalency of weak and strong secrecy conditions for a large class of secure network coding problems. When we restrict to linear operations, we show the equivalency of "perfect secrecy and zero-error constraints" with "weak secrecy and $\epsilon$-error constraints".

Includes members:
  Member "perfectly secure index coding":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "secure index coding existence and construction")
  Member "graph theory versus minimum rank for index coding":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "embedded index coding")
  Member "using feedback for secrecy over graphs":
    also connected through other hyperedges:
      (none)
  Member "on the capacity region for index coding":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "an index coding approach to caching with uncoded cache placement")
  Member "on secure network coding with nonuniform or restricted wiretap sets":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "network information theoretic security")
  Member "on secure network coding with uniform wiretap sets":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "an equivalence between secure network and index coding")
  Member "achievability proof via output statistics of random binning":
    also connected through other hyperedges:
      - Hyperedge HE-6 (induced by source paper "biometric and physical identifiers with correlated noise for controllable private authentication")
  Member "performance bounds on a wiretap network with arbitrary wiretap sets":
    also connected through other hyperedges:
      - Hyperedge HE-7 (induced by source paper "local encoding preserving secure network coding part i fixed security level")
