Title:
Automatic Proofs of Privacy of Secure Multi-Party Computation Protocols Against Active Adversaries
Authors: Martin Pettai, Peeter Laud
Abstract:We describe an automatic analysis to check secure multiparty computation protocols against privacy leaks. The analysis is sound — a protocol that is deemed private does not leak anything about its private inputs, even if active attacks are performed against it. Privacy against active adversaries is an essential ingredient in constructions aiming to provide security (privacy + correctness) in adversarial models of intermediate (between passive and active) strength. Using our analysis we are able to show that the protocols used by the Sharemind secure multiparty computation platform are actively private.
