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.
