| Abstract(in English) | Asharov et al. (Eurocrypt 2011) studied how game-theoretic concepts can be used to capture the cryptographic properties of correctness, privacy, and fairness in two-party protocols in the presence of fail-stop adversaries. Based on their work, we characterize the properties of "two-message" oblivious transfer protocols by using a game-theoretic concept. Specifically, we present a single two-player game defined by a two-message oblivious transfer protocol, and show that the game achieves a Nash equilibrium if and only if the protocol achieves the correctness and the privacy in the presence of malicious adversaries. |
