  abstract = {The cloud offers unprecedented access to computation. However,
  ensuring the privacy of that computation remains a significant challenge. In
  this paper, we address the problem of distributing computation onto the
  cloud in a way that preserves the privacy of the computation's data even
  from the cloud nodes themselves. The approach, called sTile, separates the
  computation into small subcomputations and distributes them in a way that
  makes it prohibitively hard to reconstruct the data. We evaluate sTile
  theoretically and empirically: First, we formally prove that sTile systems
  preserve privacy. Second, we deploy a prototype implementation on three
  different networks, including the globally-distributed PlanetLab testbed, to
  show that sTile is robust to network delay and efficient enough to
  significantly outperform existing privacy-preserving approaches.},
