CheapSMC: A Framework to Minimize Secure Multiparty Computation Cost in the Cloud

Secure multi-party computation (SMC) techniques are increasingly more efficient and practical, due in part, to various improvements. For instance, recent research has shown that different protocols that are implemented using different sharing mechanisms (e.g., boolean and arithmetic sharings) can have varying computational and communication costs. Although there are some approaches to automatically mix protocols of different sharing schemes to enhance execution efficiency, none provide a generic optimization framework to discover the least expensive mixed-protocol SMC execution for cloud deployment.
