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 "learning character strings via mastermind queries with a case study involving mtdna"):
  Abstract: We study the degree to which a character string Q leaks details about itself any time it engages in comparison protocols with a strings provided by a querier, Bob, even if those protocols are cryptographically guaranteed to produce no additional information other than the scores that assess the degree to which Q matches strings offered by Bob. We show that such scenarios allow Bob to play variants of the game of Mastermind with Q so as to learn the complete identity of Q. We show that there are a number of efficient implementations for Bob to employ in these Mastermind attacks, depending on knowledge he has about the structure of Q, which show how quickly he can determine Q. Indeed, we show that Bob can discover Q using a number of rounds of test comparisons that is much smaller than the length of Q, under reasonable assumptions regarding the types of scores that are returned by the cryptographic protocols and whether he can use knowledge about the distribution that Q comes from. We also provide the results of a case study we performed on a database of mitochondrial DNA, showing the vulnerability of existing real-world DNA data to the Mastermind attack.
