This addresses the need for practical, secure communication methods in cryptography and information theory, representing a novel application rather than an incremental improvement.
The authors tackled the problem of designing practical coding schemes for achieving information-theoretic security in general wiretap channels, proposing a polar coding scheme that achieves the secrecy capacity.
Information-theoretic work for wiretap channels is mostly based on random coding schemes. Designing practical coding schemes to achieve information-theoretic security is an important problem. By applying the two recently developed techniques for polar codes, we propose a polar coding scheme to achieve the secrecy capacity of the general wiretap channel.
