Practical Confidentiality Preserving Big Data Analysis

The “pay-as-you-go” cloud computing model has strong potential for efficiently supporting big data analysis jobs expressed via data-flow languages such as Pig Latin. Due to security concerns — in particular leakage of data — government and enterprise institutions are however reluctant to moving data and corresponding computations to public clouds. We present Crypsis, a system that allows execut...

Confidentiality-Preserving Refinement

We develop a condition for confidentiality-preserving refinement which is both necessary and sufficient. Using a slight extension of CSP as notation, we give a toy example to illustrate the usefulness of our condition. Systems are specified by their behavior and a window. For an abstract system, the window specifies what information is allowed to be observed by its environment. For a concrete s...
