We study efficiency tradeoffs for secure two-party computation in presence of malicious behavior. We investigate two main approaches for defending against malicious behavior in
Yao’s garbled circuit
method: (1)
Committed-input
scheme, (2)
Equality-checker
scheme. We provide asymptotic and concrete analysis of communication and computation costs of the designed protocols. We also develop a weaker definition of security (
k-leaked model
) for malicious two-party computation that allows for disclosure of some information to a malicious party. We design more efficient variations of
Yao’s
protocol that are secure in the proposed model.
