Research Abstract |
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.
