The broadcast nature of wireless communication makes it intrinsically vulnerable to
eavesdropping attacks. This article suggests the using of secret spreading codes (ie only a …

The broadcast nature of wireless communication make it intrinsically vulnerable to jamming
and eavesdropping attacks. Spread-spectrum techniques spread narrowband signals over a …

In this paper, we propose a directional spread‐spectrum modulation (DSM) signal
transmitted by a switched antenna array for physical layer security communication. The main …

Jamming resistance is crucial for applications where reliable wireless communication is
required. Spread spectrum techniques such as Frequency Hopping Spread Spectrum …

To protect confidential communications from eavesdropping attacks in wireless networks, we
propose a novel anti-eavesdropping scheme named AE-Shelter. In our proposed scheme …

Unlike passive eavesdropping, proactive eavesdropping is recently proposed to use
jamming to moderate a suspicious link's communication rate for facilitating simultaneous …

Wireless communication is vulnerable to eavesdropping attack due to the broadcast nature
of radio propagation. In recent years, physical-layer security is emerging as a promising …

Unlike conventional anti-eavesdropping methods that always require additional energy or
computing resources (eg, in friendly jamming and cryptography-based solutions), this work …

Traditional anti-jamming approaches like Frequency Hopping Spread Spectrum (FHSS) and
Direct Sequence Spread Spectrum (DSSS) require the sender and the receiver to share a …

In this paper we improve physical layer security of wireless networks with the presence of
passive eavesdropper using Alamouti code and artificial noise. Simulation results show that …
