Efficient Codes for Adversarial Wiretap Channels

Wang, Pengwei · Safavi-Naini, Reihaneh

Original · EN

In [13] we proposed a (ρᵣ, ρw)-adversarial wiretap channel model (AWTP) in which the adversary can adaptively choose to see a fraction ρᵣ of the codeword sent over the channel, and modify a fraction ρw 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.
