Abstract
RAM-model secure computation addresses the inherent limitations of
circuit-model secure computation considered in almost all previous work.
Here, we describe the first automated approach for RAM-model secure
computation in the semi-honest model. We define an intermediate
representation called SCVM and a corresponding type system suited for
RAM-model secure computation. Leveraging compile-time optimizations, our
approach achieves order-of-magnitude speedups compared to both
circuit-model secure computation and the state-of-art RAM-model secure
computation.
