We show that polar codes asymptotically achieve the whole capacity-equivocation region for
the wiretap channel when the wiretapper's channel is degraded with respect to the main …

The renewed interest for physical-layer security techniques has put forward a new role for
error-control codes. In addition to ensuring reliability, carefully designed codes have been …

For an arbitrary degree distribution pair (DDP), we construct a sequence of low-density
parity-check (LDPC) code ensembles with girth growing logarithmically in block-length using …

We consider transmission over a wiretap channel where both the main channel and the
wiretapper's channel are binary erasure channels (BEC). A code construction method is …

The paper describes a reconciliation procedure for physical key generation based on
specially designed LDPC codes using Slepian-Wolf-type coding. The LDPC codes are …

In this paper, we consider the equivocation of finite blocklength coset codes when used over
binary erasure wiretap channels. We make use of the equivocation matrix in comparing …

Wireless telemetry communication systems may be vulnerable to eavesdroppers due to their
broad-casting nature, which is a risk to confidential information transmission. This paper …

We consider code design for Wyner's wiretap channel. Optimal coding schemes for this
channel require an overall code that is capacity achieving for the main channel, partitioned …

We improve the secrecy guarantees for transmission over general binary memoryless
symmetric wiretap channels that relies on regular LDPC codes. Previous works showed that …

In this paper, we investigate the nature of the coding mechanisms required to ensure strong
secrecy over wiretap channels. Specifically, we analyze the limitations of capacity-based …
