  • Breaking an orbit-based symmetric cryptosystem 

    Solak, Ercan; Rhouma, Rhouma; Belghith, Safya Mdimegh (Pergamon-Elsevier Science LTD, 2011-09)
    We report a break for a recently proposed class of cryptosystems. The cryptosystem uses constant points of a periodic secret orbit to encrypt the plaintext. In order to break the system, it suffices to sort the constant ...
  • Cryptanalysis of image encryption with compound chaotic sequence 

    Solak, Ercan (IEEE, 2009)
    Recently, an image encryption algorithm based on compound chaotic sequence was proposed [Tong et al., Image and Vision Computing 26 (2008) 843]. In this paper, we analyze the security weaknesses of the proposal. We give ...
  • Kaotik kriptografinin çilesi 

    Solak, Ercan (IEEE, 2013)
    Despite being an active research area for the last two decades, chaotic cryptography has not found a place in mainstream cryptography literature. This paper explores the reasons for this separation.
