AI Technical Summary

Technical Problem

In large-scale MIMO scenarios without cell, the existing technology is difficult to effectively resist upstream passive eavesdropping and downstream pilot pollution attacks at the same time, and the load imbalance problem of edge servers has not been fully solved.

Method used

A network system with joint security and energy load balancing is proposed. By equipping with independent edge servers and multiple antennas in the access point AP-ES, it uses full-duplex mode and artificial noise signals to resist passive eavesdropping, and uses beamforming technology and matching matrix management to combat pilot pollution attacks, while using optimal task offload decisions and energy load balancing strategies.

Benefits of technology

It realizes efficient and secure transmission of uplink passive eavesdropping and downlink pilot pollution attacks in large-scale MIMO scenarios without cellulose, ensuring the transmission security of uplink and downlink and the load balancing of edge servers.

Abstract

The present invention discloses a network system combining security and energy load balancing, comprising: Access Points (APs): equipped with N t antennas, with L APs included. The APs are connected to the CPU through wired backhaul links. All APs serve K single-antenna User Equipments (UEs). All APs are equipped with independent Edge Servers (ESs) and form APs-ESs equipped with independent edge servers; Single-antenna attacker Eve: used to intercept legitimate information; The working mode of the APs-ESs and the attacker Eve is the full-duplex mode. The attacker Eve intercepts the uplink transmission through passive eavesdropping and intercepts the downlink transmission through active pilot contamination attacks. The APs-ESs send artificial noise signals to the attacker Eve during the uplink task offloading transmission process to resist passive eavesdropping.
