Abstract
Described is a system for mobile proactive secure multiparty computation using commitments. The system generates, at each server, secret sharings for each of its input gates using a Secret-Share protocol. Thereafter, sharings of inputs are generated for random gates using a GenPoly protocol. Sharings of multiplication triples are then generated for multiplication gates using a Multiplication-Triple protocol. Affine gates are then evaluated. Multiplication gates can then be evaluated using the multiplication triples and implementing a Secret-Open protocol. A Secret-Redistribute protocol is used to re-randomize the secret sharing. The Secret-Open protocol is implemented after a sharing for an output gate has been computed to reveal the secret.
