We provide the first two-party protocol allowing Alice and Bob to evaluate privately even against active adversaries any completely positive, trace-preserving map
, given as a quantum circuit, upon their joint quantum input state
. Our protocol leaks no more to any active adversary than an ideal functionality for
provided Alice and Bob have the cryptographic resources for active secure two-party classical computation. Our protocol is constructed from the protocol for the same task secure against specious adversaries presented in [
