Analysis on A 1-out-n Security Protocol Based on Threshold Idea

In a 1-out-n oblivious transfer model, the sender sends n messages to the receiver. But the receiver can only get 1 message from the n messages, and the sender does not know which message the receiver has gotten. In this paper, we proposed a multiple-use 1-out-n oblivious transfer protocol based on threshold idea. It is more efficient than Naor-Pinkas protocol[1] and Tzeng protocol[2].
