    Quantum cryptography is a field that investigates how quantum mechanics can be utilized to make secure communication frameworks. Quantum cryptography utilizes the laws of quantum physical science to send private data, which makes undetected snooping unimaginable. Quantum cryptography depends on photons for information transmission. A photon, in basic terms, is a solitary molecule of light. Photons address paired bits that are sent by means of fiber optic links. One quantum key requires a solitary photon laser shaft signal through a fiber optic link. Just a single photon goes through at a time, making this interaction slower than current specialized strategies. Also, quantum key circulation (QKD) requires a committed fiber optic link between the source and the beneficiary, which confounds things further.
  • Delay Normalization Technique to Disrupt Covert Timing Channels Using Active Warden
    Vrushali Uday Uttarwar, Dhananjay M. Dakhane
    EPJ Web of Conferences, 2025
    Covert channels exploit existing network resources, such as packet headers and timing information, to transfer information in ways not originally intended for communication, making them undetectable by conventional methods. This poses significant security risks, as these channels can be used maliciously despite stringent security measures like firewalls. Hence, there is a critical need for a generalized mechanism capable of blindly detecting covert communications within network traffic. We have developed a framework to evaluate covert timing channels and conducted experiments with an active warden. Our findings indicate that the active warden effectively prevents covert timing communication, demonstrating the framework's potential for enhancing network security.
  • Analysis and Mitigation of Covert Timing Communication Channels Using Active Warden Mechanism for Enhancing Network Security

    International Journal of Computational and Experimental Science and Engineering, 2025
    Covert communication channels (CCC) are very powerful challenges to the network security since they allow for unauthorized data transfer through different ways of mediation, usually avoiding traditional protections. In this study, we study and mitigate such channels through an innovative adaptive warden mechanism. Network traffic is dynamically normalized by the adaptive warden to disrupt covert signals while minimizing its effects on normal traffic data transmission. The mechanisms are evaluated to understand the encoding schemes, including Dual Bit, ON-OFF, and JitterBug, in the context of real-time scenarios. The adaptive warden mitigates CCCs through negligible overhead in transmission times; this is experimentally demonstrated with overhead consistently 1% or less. Moreover, as a contribution, the proposed framework also proposes a scalable approach to mitigating covert communication by means of protocol normalization, delay randomization, and traffic analysis. The study also highlights essential knowledge gaps when addressing CCCs in the IPv6 protocol space, highlighting the demand for improved countermeasures in contemporary network designs. The work presents a general framework for detecting and mitigating CCCs and provides a number of significant advancements in network security. It serves as a basis for future work in adaptive mechanisms to defend against emerging threats to covert communication in heterogeneous and complicated network environments.
  • A Review on Network Covert Channel Construction and Attack Detection
    Mrinal Ashish Khadse, Dhananjay Manohar Dakhane
    Concurrency and Computation Practice and Experience, 2025
    A covert network channel is a communication channel in which the message is secretly transmitted to the recipient. Sometimes, covert network channels are vulnerable to multiple attacks. Therefore, the message must be properly secure. In most cases, the covert channel is used to ensure data protection and allow users to freely access the Internet. In this paper, several recent studies are reviewed on covert network channels and examine the existing works from 2015 to 2024. This review article also discusses the undetectability and reliability of different types of covert network channels. Furthermore, a detailed description of the covert network channel's ability to hide in containers is provided. Existing research on covert network channels explains a few techniques for detecting attacks in secret data communication. However, several machine learning and deep learning techniques have been discussed in this article. Additionally, this article describes the accuracy of detection through an overview of current technologies. In addition, various countermeasures to prevent attacks in covert channels are also discussed in detail. However, in this case, the bandwidth limitations, data set limitations, and covert channel capacity are clearly defined, which will help future researchers build covert network channels and detect attacks. Finally, this work considers the challenges faced by covert network channels and the future scope of application.
  • Countering Covert Timing Channels with Active Warden Delay Normalization Technique

    2025 2nd International Conference on Integration of Computational Intelligent System Icicis 2025, 2025
    Covert channels in computer networks, especially covert timing channels, pose a significant security risk by facilitating clandestine, unauthorized data transmission that circumvents conventional detection methods. This study introduces a comprehensive framework for assessing and mitigating covert channels through smart active warden mechanism that dynamically interferes with covert timing channels through delay normalization, protocol modifications, and real-time analysis. This framework simulates authentic covert communication scenarios (Model Based CTC, and Time Replay CTC encoding etc.). Through experiments involving an active warden, we demonstrated that covert timing communications can be successfully mitigated. These results highlight the framework's effectiveness and its promise for improving overall network security.

    The software development industry extensively utilizes Docker a prominent platform image containerization. Therefore, it is imperative to guarantee the security of these containerized applications. As a result, various container scanning technologies exist for identifying container security flaws. This study examines static and dynamic scanners, the prevalent tools for analyzing Docker images. The paper will present a comprehensive comparison of the advantages and disadvantages of several types of scanners, accompanied by real-world examples of their application in securing containerized applications. This study paper intends to analyze four prominent open-source vulnerability tools: Snyk, Swift, Trivy, and Grype. The report will present a comprehensive comparison of the characteristics and capabilities of each scanner, including their accuracy, usability, use cases, best practices, limitations, and potential future developments.
