In this work, we investigate the problem of private statistical analysis in the distributed and semi-honest setting. In particular, we study properties of Private Stream Aggregation schemes, first introduced by Shi et al. [27]. These are computationally secure protocols for the aggregation of data in a network and have a very small communication cost. We show that such schemes can be built upon...

Over the last decade there have been great strides made in developing techniques to compute functions privately.

In response to rising public awareness of information privacy, principles addressing the privacy of information have evolved and converged around a set of basic principles such as, for example, the Code of Fair Information Practice. Legislative developments such as the 1995 European Union's enactment of the Data Privacy Directive and the U.S. Health Insurance Portability and Accountability Act ...

Norwegian nationwide Internet voting will make use of a setting that we will call the codeverification voting. The concrete protocol that will be used in Norway was proposed by Scytl and improved by Gjøsteen. As we show, Gjøsteen’s protocol has several undesirable properties. In particular, one of the online servers shares the secret key with the offline tallier. Even without considering that, ...
