- We present a fully-verified toolchain for the secure function evaluation of (restricted) C programs between two untrusted parties. This a certified optimising compiler from C to Boolean circuits and a verifiably-secure implementation of Yao's garbled circuit protocol. This is significant for two main reasons: it demonstrates that i) machine-checked security techniques are now applicable to complex high-level cryptographic functionalities; and ii) the main cost of formal certification and machine-checking in this setting is only a one-off cost of producing the proof, with little to no runtime cost in practice.
