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 "invertible extractors and wiretap protocols"):
  Abstract: A wiretap protocol is a pair of randomized encoding and decoding functions such that knowledge of a bounded fraction of the encoding of a message reveals essentially no information about the message, while knowledge of the entire encoding reveals the message using the decoder. In this paper we study the notion of efficiently invertible extractors and show that a wiretap protocol can be constructed from such an extractor. We will then construct invertible extractors for symbol-fixing, affine, and general sources and apply them to create wiretap protocols with asymptotically optimal trade-offs between their rate (ratio of the length of the message versus its encoding) and resilience (ratio of the observed positions of the encoding and the length of the encoding). We will then apply our results to create wiretap protocols for challenging communication problems, such as active intruders who change portions of the encoding, network coding, and intruders observing arbitrary boolean functions of the encoding. #R##N#As a by-product of our constructions we obtain new explicit extractors for a restricted family of affine sources over large fields (that in particular generalizes the notion of symbol-fixing sources) which is of independent interest. These extractors are able to extract the entire source entropy with zero error. #R##N#Keywords: Wiretap Channel, Extractors, Network Coding, Active Intrusion, Exposure Resilient Cryptography.
