Abstract:

This work proposes the first feasible solutions for secure multi-party computation with real numbers in floating point representation. It also provides techniques for performing more complex operations such as square root, logarithm, and exponentiation. Our experiments show that not only are the proposed protocols efficient, but in certain cases they outperform operations on integers.
