  • Cryptanalysis of Fridrich\'s chaotic image encryption 

    Solak, Ercan; Çokal, Cahit; Yıldız, Olcay Taner; Bıyıkoğlu, Türker (WORLD SCIENTIFIC PUBL CO PTE LTD, 2010-05)
    We cryptanalyze Fridrich's chaotic image encryption algorithm. We show that the algebraic weaknesses of the algorithm make it vulnerable against chosen-ciphertext attacks. We propose an attack that reveals the secret ...
  • 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 ...
