  • New class of chaotic systems with equilibrium points like a three-leaved clover 
    Saleh Mobayen; Christos K. Volos; Kaçar, Sezgin; Çavuşoğlu, Ünal (SPRINGER, 2018)
    This paper presents a new class of chaotic systems with infinite number of equilibrium points like a three-leaved clover. They signify an exciting class of dynamical systems which represent many major characteristics of ...
  • S-Box Based Image Encryption Application Using a Chaotic System without Equilibrium 
    Xiong Wang; Çavuşoğlu, Ünal; Sezgin Kacar; Akgül, Akif (MDPI, 2019)
    Chaotic systems without equilibrium are of interest because they are the systems with hidden attractors. A nonequilibrium system with chaos is introduced in this work. Chaotic behavior of the system is verified by phase ...
  • Secure image encryption algorithm design using a novel chaos based S-Box 
    Çavuşoğlu, Ünal; Kaçar, Sezgin; Pehlivan, İhsan; Zengin, Ahmet (PERGAMON-ELSEVIER SCIENCE LTD, 2017)
    In this study, an encryption algorithm that uses chaos based S-BOX is developed for secure and speed image encryption. First of all, a new chaotic system is developed for creating S-Box and image encryption algorithm. Chaos ...
  • The design and implementation of hybrid RSA algorithm using a novel chaos based RNG 
    Çavuşoğlu, Ünal; Akgül, Akif; Zengin, Ahmet; Pehlivan, İhsan (PERGAMON-ELSEVIER SCIENCE LTD, 2017)
    The number of attempts to break modern encryption methods increases day by day and therefore the need for the design of systems to ensure higher security has occurred. This study aims, an encryption algorithm that combines ...
