  In this paper, we study the problem of the 1-of-2 string oblivious transfer
(OT) between Alice and Bob in the presence of a passive eavesdropper Eve. The
eavesdropper Eve is not allowed to get any information about the private data
of Alice or Bob. When Alice and Bob are honest-but-curious users, we propose a
protocol that satisfies $1$-private (neither Alice nor Bob colludes with Eve)
OT requirements for the binary erasure symmetric broadcast channel, in which
the channel provides dependent erasure patterns to Bob and Eve. We find that
when the erasure probabilities satisfy certain conditions, the derived lower
and upper bounds on the wiretapped OT capacity meet. Our results generalize and
improve upon the results on wiretapped OT capacity by Mishra et al. Finally, we
propose a protocol for a larger class of wiretapped channels and derive a lower
bound on the wiretapped OT capacity.
