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 …

This paper lays the foundations for Physical Layer Security (PLS) as a native 6G
communication operation mode. 6G mobile network will enable intelligent applications …

We survey the state-of-the-art on the Internet-of-Things (IoT) from a wireless communications
point of view, as a result of the European FP7 project BUTLER which has its focus on …

The generation of secret keys from reciprocal wireless channel by exploiting their
randomness nature, is an emerging area of interest to provide secure communication. One …

Although the visible light communication (VLC) channel has superior security than radio
frequency channels, its broadcast character makes VLC links vulnerable to eavesdropping …

It is well known that physical-layer Group Secret-Key (GSK) generation techniques allow
multiple nodes of a wireless network to synthesize a common secret-key, which can be …

A new chaotic encryption algorithm is proposed. Its key is based on chaotic sequence and
plain text. First, the chaotic sequence and the plain text are used; the result is the key, so …

Due to the unavoidable shared nature of the wireless radio spectrum, providing security for
wireless communications presents unique challenges. Cryptographic keys have been used …

Physical layer key generation is a lightweight technique to establish secret keys securely
between resource-constrained devices, but it is ineffective when wireless channels are static …

Automotive cyber physical systems (CPSs) are ever more utilizing wireless technology for
V2X communication as a potential way out for challenges regarding collision detection, wire …
