One of the most challenging aspects in secure computation is offering protection against active adversaries, who may arbitrarily alter the behavior of corrupted parties. A powerful paradigm due to Goldreich, Micali, and Wigderson (GMW), is to follow a two-step approach: (1) design a passively secure protocol π for the task at hand; (2) apply a general compiler to convert π into an actively secure protocol π' for the same task.
