Secure Computation is not what I think.
Generally speaking, secure computation is to let 2(or more) mutually distrusted parties compute on both parties' data without exposing the plaintext of the data.
This problem originates in this paper: Protocols for Secure Computations (PDF). The famous millionaires' problem came from this paper and then Garbled Circuit(Wiki) became popular in this field. Dr. Qizhi Yao is the initiator of field and he is also the founder of several other fields in crypto and computer theory.
