Computationally Sound Abstraction and Verification of Secure Multi-Party Computations

Abstract

We devise an abstraction of secure multi-party computations in the applied $\pi$-calculus. Based on this abstraction, we propose a methodology to mechanically analyze the security of cryptographic protocols employing secure multi-party computations. We exemplify the applicability of our framework by analyzing the SIMAP sugar-beet double auction protocol. We finally study the computational soundness of our abstraction, proving that the analysis of protocols expressed in the applied $\pi$-calculus and based on our abstraction provides computational security guarantees.
