• Collaborative agent-based detection of DDoS IoT botnets 

      Giachoudis N., Damiris G.-P., Theodoridis G., Spathoulas G. (2019)
      The Internet of Things constitutes the latest paradigm shift in computing. Billions of devices sense the real world and store produced data in the cloud. Existing security models, approaches and solutions are not able to ...
    • Collaborative blockchain-based detection of distributed denial of service attacks based on internet of things botnets 

      Spathoulas G., Giachoudis N., Damiris G.-P., Theodoridis G. (2019)
      Internet of Things is one of the most significant latest developments in computer science. It is common for modern computing infrastructures to partially consist of numerous low power devices that are characterized by high ...
    • Fingerspelled alphabet sign recognition in upper-body videos 

      Papadimitriou K., Potamianos G. (2019)
      Fingerspelling is a crucial part of sign-based communication, however its recognition remains a challenging and mostly overlooked computer vision problem. To address it, this paper presents a system that recognizes the 24 ...
    • A framework for MAC protocol misbehavior detection in wireless networks 

      Radosavac, S.; Baras, J. S.; Koutsopoulos, I. (2005)
      The pervasiveness of wireless devices and the architectural organization of wireless networks in distributed communities, where no notion of trust can be assumed, are the main reasons for the growing interest in the issue ...
    • Machine Learning for Hardware Trojan Detection: A Review 

      Liakos K.G., Georgakilas G.K., Moustakidis S., Karlsson P., Plessas F.C. (2019)
      Every year, the rate at which technology is applied on areas of our everyday life is increasing at a steady pace. This rapid development drives the technology companies to design and fabricate their integrated circuits ...
    • New results on turbulence modeling for free-space optical systems 

      Chatzidiamantis, N. D.; Sandalidis, H. G.; Karagiannidis, G. K.; Kotsopoulos, S. A.; Matthaiou, M. (2010)
      In this paper, we propose a statistical channel model, named as Double-Weibull, to describe the irradiance fluctuations in moderate and strong turbulence for free-space optical (FSO) systems. The proposed stochastic model ...
    • A simple statistical model for turbulence-induced fading in free-space optical systems 

      Chatzidiamantis, N. D.; Sandalidis, H. G.; Karagiannidis, G. K.; Matthaiou, M. (2010)
      In this paper, we propose the Inverse Gaussian (IG) distribution, as a less complex alternative to Log-normal (LN), to describe turbulence-induced fading in free-space optical (FSO) systems operating in weak turbulence ...
