  In [13] we proposed a ({\rho}_r , {\rho}_w )-adversarial wiretap channel
model (AWTP) in which the adversary can adaptively choose to see a fraction
{\rho}_r of the codeword sent over the channel, and modify a fraction {\rho}_w
of the codeword by adding arbitrary noise values to them. In this paper we give
the first efficient construction of a capacity achieving code family that
provides perfect secrecy for this channel.
