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 "extension of overbeck s attack for gabidulin based cryptosystems"):
  Abstract: We present a new attack against cryptosystems based on the rank metric. Our attack allows us to cryptanalyze two variants of the GPT cryptosystem which were designed to resist the attack of Overbeck.

Includes members:
  Member "new criteria for mrd and gabidulin codes and some rank metric code constructions":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "decoding high order interleaved rank metric codes")
  Member "equivalence for rank metric and matrix codes and automorphism groups of gabidulin codes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "equivalence and characterizations of linear rank metric codes based on invariants")
