A cryptographic protocol called oblivious transfer is a powerful tool in secure multiparty computation. In this research project, we studied unconditionally secure oblivious transfer whose secrecy is guaranteed even when a malicious player has unlimited computational power. We designed a procedure between two parties for realizing oblivious transfer by assuming the existence of continuous noisy channels. An efficient coding scheme to be used in this scenario is also proposed.

不经意传输协议是安全多方计算的有力工具。在这个研究项目中，我们研究了无条件安全的不经意传输，即使恶意玩家具有无限的计算能力，其保密性也得到保证。我们设计了一个过程，在双方之间实现不经意传输的假设存在连续的噪声信道。还提出了在这种情况下使用的高效编码方案。
