Analysis Of The Simulatability Of An Oblivious Transfer

Bing Zeng

Abstract: In the Journal of Cryptology (25(1): 158-193. 2012), Shai Halevi and Yael Kalai proposed a general framework for constructing two-message oblivious transfer protocols using smooth projective hashing. The authors asserts that this framework gives a simulation-based security guarantee when the sender is corrupted. Later this work has been believed to be half-simulatable in literatures. In this paper, we show that the assertion is not true and present our ideas to construct a fully-simulatable oblivious transfer framework.
