BMR Protocol
The BMR protocols adapt the main idea of Yao’s Garbled Circuit to a multi-party setting. The basic idea is that another MPC protocol is used to generate an n-party garbling, and then each player independently evaluate the circuit. To obtain active security one needs to utilize an actively secure base MPC protocol, and in addition utilize a method to ensure the evaluation phase reveals any deviations from the protocol. In modern BMR protocols the underlying MPC protocol is usually based on the n-party variant of Tiny-OT.
