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 "Non-Interactive Secure Computation Based on Cut-and-Choose"):
  Abstract: In recent years, secure two-party computation (2PC) has been demonstrated to be feasible in practice. However, all efficient general-computation 2PC protocols require multiple rounds of interaction between the two players. This property restricts 2PC to be only relevant to scenarios where both players can be simultaneously online, and where communication latency is not an issue.

Includes members:
  Member "Blazing Fast 2PC in the Offline/Online Setting with Security for Malicious Adversaries":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "Cryptography and game theory: designing protocols for exchanging information")
  Member "More Efficient Constant-Round Multi-party Computation from BMR and SHE":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "Authenticating Computation on Groups: New Homomorphic Primitives and Applications")

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.
