Cut-and-choose protocols can be optimized by considering them as adversarial games.

Square-Root ORAM

Square-Root ORAM provides more efficient access and initialization for SC-RAM applications across a wide range of parameters.

Two Halves Make a Whole

Surprisingly, it is possible to reduce the data needed for a garbled gate to only two ciphertexts per gate, while preserving free xors. The scheme for doing that is described in our paper, Two Halves Make a Whole: Reducing Data Transfer in Garbled Circuits using Half Gates by Samee Zahur...
