human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Secure Multiparty Computation Goes Live"):
  Abstract: In this note, we report on the first large-scale and practical application of secure multiparty computation, which took place in January 2008. We also report on the novel cryptographic protocols that were used.

Includes members:
  Member "Multiparty computation for dishonest majority: from passive to active security at low cost":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "Fast computation on encrypted polynomials and applications")
  Member "General secure multi-party computation from any linear secret-sharing scheme":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "Secure outsourced computation of iris matching")

Question: Please tell me which research area the co-authored paper (i.e., the source paper of the center hyperedge) belongs to. The 4 classes are: Computer science, Mathematics, Engineering, Economics, Psychology, Business. Directly output the class name.
