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.

Reversible and Plausibly Deniable Covert Channels in One-Time Passwords Based on Hash Chains
Applied Sciences, 2021 Covert channels enable stealthy communications over innocent appearing carriers. They are increasingly applied in the network context. However, little work is available that exploits cryptographic primitives in the networking context to establish such ...

A Two-Way VoLTE Covert Channel With Feedback Adaptive to Mobile Network Environment
IEEE Access, 2019 In the existing network covert channel research, the transmission of secret messages is one-way, lacking confirmation feedback on whether the secret message is successfully accepted. However, voice over LTE (VoLTE) has real-time interactive features, and
