Abstract: Successful deployment of privacy preserving collaborative applications, like statistical analysis, benchmarking, and optimizations, requires more efficient secure computation with real numbers. We present a complete family of protocols for secure floating-point arithmetic, constructed using a small set of building blocks that preserve data privacy using well known primitives based on Shamir secret sharing and related cryptographic techniques. Using new building blocks and optimizations and simpler secure fixed-point arithmetic, we obtain floating-point protocols with substantially improved efficiency.
