Survey on key technologies of covert channel in ubiquitous network environment
Tongxin xuebao, 2022 In the ubiquitous network environment, covert channel bypasses the system’s security strategy to transmit covert information by modifying the system’s shared resources, which poses a serious security threat to the computer and network system.The ...

A Novel Covert Channel for IEEE 802.11 Networks Utilizing MAC Address Randomization
Applied Sciences, 2023 Vendors implement the MAC address randomization technique to prevent IEEE 802.11 client station devices from being tracked. Although it conceals device identity, it cannot hide its occurring data transmission.
