Authentication is an important issue in wireless communications because the open nature of
the wireless medium provides more security vulnerabilities. Recently, Physical-Layer …

Physical layer security (PLS) in wireless communication systems has attracted extensive
research attentions in recent years. Unlike cryptography-based methods applied in upper …

This paper concerns the problem of authenticating the transmitter without a secret key. In
comparison with traditional cryptographic-based authentication mechanisms, the Physical …

Resorting to the exploitation of physical attributes, physical-layer authentication (PLA) is a
promising technology to supplement and enhance current cryptography-based security …

While the open nature of radio propagation enables convenient “anywhere” wireless access,
it becomes the root of security vulnerabilities in wireless communications. In light of this …

The wireless physical-layer identification (WPLI) techniques utilize the unique features of the
physical waveforms of wireless signals to identify and classify authorized devices. As the …

Performance of the existing physical layer authentication schemes could be severely
affected by the imperfect estimates and variations of the communication link attributes used …

The heterogeneous characteristics of wireless mobile networks within the Internet of things
(IoT) create authentication challenges due to the large number of devices with diverse …

The wireless medium offers many opportunities for broadcast communications. However, it
also opens the possibility for attackers to eavesdrop the broadcast data or to pretend to be …

A novel physical layer authentication enhancement scheme is proposed in this paper by
integrating multipath delay characteristics of wireless channels into the channel impulse …
