In this paper, we investigate a secure mobile edge computing (MEC) network in the
presence of multiple eavesdroppers, where multiple users can offload parts of their tasks to …

This paper focuses on the multiple-input-multiple-output (MIMO) two-way relay system with
an untrusted relay and investigates its secure and energy-efficient precoding design issue …

For the security challenges generated by the eavesdroppers existing in wireless
communication systems, we propose a model for securely exchanging data between two …

In the traditional physical layer encryption methods, both the delay and errors brought by the
keys generation and interaction and those from the channel estimation are too high to be …

The PLS technology is highly promising for implementing secure communication in wireless
systems due to its advantages of easy deployment, low complexity, and everlasting secrecy …

In the coming sixth generation (6G) wireless communications, uplink multiuser massive
multiple-input and multiple-output (MIMO) systems face serious physical layer security risks …
