Secure and Private Function Evaluation with Intel SGX

Secure function evaluation (SFE) allows two parties to jointly evaluate a publicly known function without revealing their respective inputs. SFE can be realized via well-known cryptographic protocols, such as Yao's garbled circuits (GC) and the protocol of Goldreich, Micali, and Wigderson (GMW), which obliviously evaluate a Boolean circuit representation of the function. Unfortunately, even with the most recent optimizations that touch known lower bounds, these protocols incur an impractical high communication overhead.
