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 "revisiting and evaluating software side channel vulnerabilities and countermeasures in cryptographic applications"):
  Abstract: We systematize software side-channel attacks with a focus on vulnerabilities and countermeasures in the cryptographic implementations. Particularly, we survey past research literature to categorize vulnerable implementations, and identify common strategies to eliminate them. We then evaluate popular libraries and applications, quantitatively measuring and comparing the vulnerability severity, response time and coverage. Based on these characterizations and evaluations, we offer some insights for side-channel researchers, cryptographic software developers and users. We hope our study can inspire the side-channel research community to discover new vulnerabilities, and more importantly, to fortify applications against them.
