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 "secure multiplex coding with a common message"):
  Abstract: We determine the capacity region of the secure multiplex coding with a common message, and evaluate the mutual information and the equivocation rate of a collection of secret messages to the second receiver (eavesdropper), which were not evaluated by Yamamoto et al.

Includes members:
  Member "exponential decreasing rate of leaked information in universal random privacy amplification":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "communication for generating correlation a unifying survey")
  Member "universally attainable error and information exponents and equivocation rate for the broadcast channels with confidential messages":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "polar codes simplicity random codes durability")
  Member "secure multiplex network coding":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "secure network code for adaptive and active attacks with no randomness in intermediate nodes")
  Member "strong security and separated code constructions for the broadcast channels with confidential messages":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "plausible deniability over broadcast channels")
  Member "secure multiplex coding to attain the channel capacity in wiretap channels":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "secure multiplex coding with dependent and non uniform multiple messages")
