Construction of m-out-of-n Oblivious Transfer
Zhide Chen · Journal of Chinese Computer Systems · 2006
Oblivious transfer(OT)is used as a key component in many applications of cryptography. In this paper, a1-out-of-n oblivious transfer is constructed based on the sub protocol 1-out-of-2 oblivious transfer;an m-out-of-n oblivious transfer is constructed based on the sub protocol 1-out-of-n oblivious transfer. Finally,a1-out-of-2 oblivious transfer is constructed based on public key system. By this way,any existed public key system can be used to construct m-out-of-n oblivious transfer.
