  • GLOBECOM - Secure Gateway localization and communication system for vehicular ad hoc networks
    2012 IEEE Global Communications Conference (GLOBECOM), 2012
    Co-Authors: Kaouther Abrougui, Azzedine Boukerche, Yan Wang
    Abstract:

    Internet access from vehicular networks is a very promising subject that needs to be investigated from the research community. Vehicles should be able to connect to the Internet, and provide drivers and passengers with a high number of services that need communication through Gateways. Existing discovery protocols in VANets did not focus on Secure Gateway discovery in particular, but they considered the discovery of Secure services in general. In this paper, we propose a Secure hybrid adaptive Gateway discovery and communication system for VANets that we call SEGAL. Our proposed SEGAL protocol aims to provide an efficient and Secure Gateway advertisement and discovery process for VANets. It is hybrid because it combines both proactive and reactive discovery approaches. Besides, it is adaptive because it shrinks or extends the advertisement zone of the Gateway for scalability purposes. Our proposed protocol builds a Secure clustered VANet and permits the exchange of Gateway discovery messages through authenticated clusterheads and cluster members. We discuss the design of our protocol, and how it can overcome the possible attacks that can occur. Then we prove its efficiency and scalability in our performance evaluation. We show that our proposed SEGAL achieves high success rate, low response time and dropping rate, while maintaining the scalability in the VANet.

  • LineCAPTCHA Mobile: A User Friendly Replacement for Unfriendly Reverse Turing Tests for Mobile Devices (ICIAfS14)
    arXiv: Human-Computer Interaction, 2014
    Co-Authors: C. B Bulumulla, R. G Ragel
    Abstract:

    As smart phones and tablets are becoming ubiquitous and taking over as the primary choice for accessing the Internet worldwide, ensuring a Secure Gateway to the servers serving such devices become essential. CAPTCHAs play an important role in identifying human users in internet to prevent unauthorized bot attacks. Even though there are numerous CAPTCHA alternatives available today, there are certain drawbacks attached with each alternative, making them harder to find a general solution for the necessity of a CAPTCHA mechanism. With the advancing technology and expertise in areas such as AI, cryptography and image processing, it has come to a stage where the chase between making and breaking CAPTCHAs are even now. This has led the humans with a hard time deciphering the CAPTCHA mechanisms. In this paper, we adapt a novel CAPTCHA mechanism named as LineCAPTCHA to mobile devices. LineCAPTCHA is a new reverse Turing test based on drawing on top of Bezier curves within noisy backgrounds. The major objective of this paper is to report the implementation and evaluation of LineCAPTCHA on a mobile platform. At the same time we impose certain security standards and security aspects for establishing LineCAPTCHAs which are obtained through extensive measures. Independency from factors such as the fluency in English language, age and easily understandable nature of it inclines the usability of LineCAPTCHA. We believe that such independency will favour the main target of LineCAPTCHA, user friendliness and usability.

  • Secure Real-time Communication and Computing Infrastructure for Industry 4.0 — Challenges and Opportunities
    2019 International Conference on Networked Systems (NetSys), 2019
    Co-Authors: Erich Zielinski, Julius Schulz-zander, Marc Zimmermann, Christian Schellenberger, Alejandro Ramirez, Florian Zeiger, Mathias Mormul, Felicitas Hetzelt, Felix Beierle, Harald Klaus
    Abstract:

    In this experience paper, we summarize the analysis of key technologies that are prerequisite for a Secure realtime communication and computing Infrastructure in the smart factory, which supports flexible and reconfigurable production assets with a real-time digital representation. A broad range of Industry 4.0 use cases is evaluated - jointly with industrial application partners - and a set of basic requirements is derived from them. These challenges need to be addressed by available and upcoming ICT technologies in the domains of cloud computing in an industrial environment, virtualization and industrial Edge Computing, 5G radio and network, analytics with big and fast data, and Artificial Intelligence / Machine Learning technologies. The analysis includes mechanisms for Secure and reliable connectivity in production, Secure wireless communication and Secure processes, massive sensor data analysis, and (virtual) network elements like Secure Gateway. Challenges and opportunities for new applications in production are described in the following.
