  1. 这篇论文最主要的创意是什么?
    1. Present a new garbled circuit in semi-honest. XOR gates are evaluated “for free”, which results in the corresponding improvement over the best garbled circuit implementations
  2. 这些创意在应用上有什么好处?
    1. this results in a factor of up to 4 improvement (in both computation and communication) of their SFE. 性能提高4倍
  3. 这些创意和应用上的好处是在哪些条件下才能成立?(论文建立在什么条件之上)?
    1. One area of SFE that especially benefits from our work is the SFE of private functions (PF-SFE). It is an extension of SFE where the evaluated function is known only by one party and needs to be kept secret.(对于那种 evaluated function is known only by one party and needs to be kept secret有用)
    2. rely on the RO assumption
