A 1-out-n Oblivious Transfer(OT)Protocol Based on Threshold Idea

In a 1-out-n oblivious transfer(OT)model,the sender sends n messages to the receiver.The receiver only get 1 message from n messages.However,the sender cannot know which message the receiver got.In this paper,we proposed a multiple-use 1-out-n oblivious transfer scheme based on threshold idea.It is more efficient than Naor-Pinkas scheme and Tzeng scheme.
