Abstract: At Financial Crypto 2006, Golle presented a novel framework for the privacy preserving computation of a stable matching (stable marriage). We show that the communication complexity of Golle's main protocol is substantially greater than what was claimed in that paper, in part due to surprising pathological behavior of Golle's variant of the Gale-Shapley stable matching algorithm. We also develop new protocols in Golle's basic framework with greatly reduced communication complexity.
