In this work, we consider the pros and cons of using various layers of keyless coding to
achieve secure and reliable communication over the Gaussian wiretap channel. We define a …

For physical-layer secrecy performance, existing studies only focus on coding schemes that
can achieve the secrecy capacity. However, finite blocklength penalty could be fatal for …

While secrecy in communication systems has historically been obtained through
cryptographic means in the upper layers, recent research efforts have focused on the …

In this paper, we fill a void between information theoretic security and practical coding over

In this paper, we investigate the binary symmetric wiretap channel. We show that the secrecy

We design short blocklength codes for the Gaussian wiretap channel under information-

We derive lower bounds to the second-order coding rates for the wiretap channel. The

We study the problem of achieving strong secrecy over wiretap channels at negligible cost,
in the sense of maintaining the overall communication rate of the same channel without …
