Hongrui Cui, Xiao Wang, Kang Yang, Yu Yu

Actively secure two-party computation (2PC) is one of the canonical building blocks
in modern cryptography. One main goal for designing actively secure 2PC protocols is to reduce the communication overhead, compared to semi-honest 2PC protocols.
In this paper, we propose a new actively secure constant-round 2PC protocol with one-way communication of $2\kappa+5$ bits per AND gate (for $\kappa$-bit computational
security and …
