Abstract

Upper and lower bounds to the oblivious transfer (OT) capacity of discrete memoryless channels and multiple sources are obtained, for 1 of 2 strings OT with honest but curious participants. The upper bounds hold also for one-string OT. The results provide the exact value of OT capacity for a specified class of models, and the necessary and sufficient condition of its positivity, in general.
