Introducing asymmetric DC-Nets

This preliminary work lies in the intersection between DC-Nets and additive homomorphic encryptions. Both approaches are used to protect users´ privacy. We introduce the concept of asymmetric DC-Nets that has good property of both approaches. Moreover, we construct one protocol based on integer numbers that fulfills all requirements to be classified as an asymmetric DC-Net. Many other protocols might be constructed to fulfill these requirements. Since asymmetric DC-Nets provide privacy-preserving aggregation of time-series data with verification, they have potential to be applied to e-voting, reputation systems, sensor networks, multi-party computation, and smart grids, among other application scenarios.
