Format: PDF
In the various 1-out-of-n Distributed Oblivious Transfer protocols (DOT) designed in an unconditionally secure environment, a receiver contacts k out of m servers to obtain one of the n secrets held by a sender. After a protocol has been executed, the sender has no information on the choice of the receiver and the receiver has no information on the secrets they did not obtain. Likewise, a coalition of k - 1 servers is unable to infer any information, neither on the sender's secrets, nor on the receiver's choice.
