TCP covert timing channels: Design and detection [PDF]
2008 IEEE International Conference on Dependable Systems and Networks With FTCS and DCC (DSN), 2008 Exploiting packetspsila timing information for covert communication in the Internet has been explored by several network timing channels and watermarking schemes. Several of them embed covert information in the inter-packet delay. These channels, however, can be detected based on the perturbed traffic pattern, and their decoding accuracy could be ...

Detection of Covert Channels Over ICMP Protocol [PDF]
2017 IEEE/ACS 14th International Conference on Computer Systems and Applications (AICCSA), 2017 With the growing complexity of networks and communications protocols that become increasingly enormous and extensive, we are confronted with the problem of covert channel that affects the confidentiality and integrity of data sent in the network. Covert channels also known as hidden channels can elude basic security systems such as Intrusion Detection ...

Proactive Eavesdropping via Covert Pilot Spoofing Attack in Multi-Antenna Systems
IEEE Access, 2019 Proactive eavesdropping is an effective method for government to monitor suspicious users who are deemed to misuse communication systems for illegal activities. In this paper, considering that a legitimate full-duplex (FD) eavesdropper tries to monitor a

Covert Channel Based on Quasi-Orthogonal Coding
, 2023 The paper presents a method of creating a hidden channel using a signals’ superposition. According to this idea, a transmitter simultaneously sends overt and covert (secret) signals, whereby the overt signal is a carrier for the covert one.

Performance Comparison of Relay-Based Covert Communications: DF, CF and AF
Sensors, 2023 In this paper, we investigate the performance of covert communications in different types of a relay system: decode-and-forward (DF), compress-and-forward (CF) and amplify-and-forward (AF).

Detecting Covert Channels Through Code Augmentation [PDF]
, 2021 Modern malware increasingly exploits information hiding or steganography to elude security frameworks and remain unnoticed for long periods. To this aim, a prime technique relies upon the ability of creating covert channels to bypass the limits imposed by a sandbox or to exfiltrate data towards a remote server. Unfortunately, detecting a covert channel
