Combining Secret Sharing and Garbled Circuits for Efficient Private IEEE 754 Floating-Point Computations

Pille Pullonen and Sander Siim

Abstract: Two of the major branches in secure multi-party computation research are secret sharing and garbled circuits. This work succeeds in combining these to enable seamlessly switching to the technique more efficient for the required functionality. As an example, we add garbled circuits based IEEE 754 floating-point numbers to a secret sharing environment achieving very high efficiency and the first, to our knowledge, fully IEEE 754 compliant secure floating-point implementation.

Category / Keywords: cryptographic protocols / secure multi-party computation, garbled circuits, secret sharing, floating-point numbers
