Secure two-party computation (2PC) in the RAM model has attracted huge attention in recent years. Most existing results only support semi-honest security, with the exception of Keller and Yanai (Eurocrypt 2018) with very high cost. In this paper, we propose an efficient RAM-based 2PC protocol with active security and one-bit leakage.


1) We propose an actively …
