Abstract
Described is system for secure mobile proactive multi-party computation. The system securely evaluates a circuit in the presence of an adversary. The circuit receives secret inputs comprising secret values from a set of servers. Sharings of random values for the random and input gates are generated. For each input gate, a sharing of a random value associated with the input gate is opened toward a server P. A sum of the server P's secret values and the random value is broadcast to the set of servers. Each server uses the sum to adjust its sharing of the random value, generating a sharing of server P's secret values. The secret values are re-randomized to preserve privacy of the secret values. A sharing of the secret values is determined for each output gate, and each sharing of secret values is revealed to an intended recipient.
