Abstract :
The concept of oblivious transfer capacity has been recently introduced by Nascimento and Winter. We give an upper bound to this capacity, both for source and channel models, and prove that it is tight for a class of channels. For other cases, lower bounds are provided. The tools include known results on secrecy capacity of simple source and channel models.
