An Insight to Covert Channels
This is an incremental review paper that synthesizes existing knowledge on covert channels for researchers and practitioners in cybersecurity.
The paper provides an overview of covert channels, including classifications, evaluation criteria, defenses, and an advanced temperature-based timing channel, without presenting new experimental results or specific numerical findings.
This paper presents an overview of different concepts regarding covert channels. It discusses the various classifications and the detailing of various fields used to manipulate for the covert channel execution.Different evaluation criterias are presented for measuring the strength of covert channels. The defenses and prevention schemes for this covert channel will also be discussed. This paper also discuss about an advanced timing channel i.e.Temperature Based Covert Channel.
