Abstract
An encryption system and method are provided that provide the ability to execute a secure multi-party computation (SMPC) protocol to compute a large function using check points. At each checkpoint, respective parties to the computation write out some encrypted data that can be used to initiate the next stage of the computation between the present check point and the next check point. In this manner, if any participating party experiences a failure, such as a network outage, system crash, disk corruption, etc., during the protocol execution, there is no need to re-start the entire protocol from scratch. This allows for large functions to be practically computed using SMPC.
