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 "multiparty probability computation and verification"):
  Abstract: A multiparty computation protocol is described in which the parties can generate different probability events that is based on the sharing of a single anonymized random number, and also perform oblivious transfer. A method to verify the correctness of the procedure, without revealing the random numbers used by the parties, is proposed.

Includes members:
  Member "a review of man in the middle attacks":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "coding side information for implementing cubic transformation")
  Member "oblivious transfer protocol with verification":
    also connected through other hyperedges:
      (none)
  Member "generating primes using partitions":
    also connected through other hyperedges:
      (none)
  Member "a survey of p2p network security":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a review of man in the middle attacks")
  Member "survey of sybil attacks in social networks":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "coding side information for implementing cubic transformation")
  Member "the piggy bank cryptographic trope":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "secret sharing with trusted third parties using piggy bank protocol")
