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 "efficient one way secret key agreement and private channel coding via polarization"):
  Abstract: We introduce explicit schemes based on the polarization phenomenon for the task of secret-key agreement from common information and one-way public communication as well as for the task of private channel coding. Our protocols are distinct from previously known schemes in that they combine two practically relevant properties: they achieve the ultimate rate--defined with respect to a strong secrecy condition--and their complexity is essentially linear in the blocklength. However, we are not able to give an efficient algorithm for code construction.
