Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

Information theoretic approaches to security have been examined as a promising
complement to current cryptographic techniques. Such information theoretic approaches …

We develop a low-complexity polar coding scheme for the discrete memoryless broadcast
channel with confidential messages under strong secrecy and randomness constraints. Our …

A method to polarize channels universally is introduced. The method is based on combining
channels of unequal capacities in each polarization step, as opposed to the standard …

We consider strongly secure communication over a discrete memoryless multiple access
wiretap channel with two transmitters. No degradation or symmetry assumptions are made …

Next-generation wireless networks aim to enable order-of-magnitude increases in
connectivity, capacity, and speed. Such a goal can be achieved in part by utilizing larger …

We consider wiretap channels with uncertainty on the eavesdropper channel under (i) noisy
blockwise type II,(ii) compound, or (iii) arbitrarily varying models. We present explicit wiretap …

Robust biometric authentication is studied from an information theoretic perspective.
Compound sources are used to account for uncertainty in the knowledge of the source …
