| Abstract | In this paper, the security performance for an 8D self-synchronous and feedback-based chaotic stream cipher with the low 8 bits of state variables for encryption is analyzed. According to known-plaintext attack and divide-and-conquer attack, only the second plain-pixel and its corresponding cipher-pixel are required to decipher the secret keys (a) over cap (1i), (a) over cap (2i), (a) over cap (3i) (i = 1, 2, ... , 8) by properly setting 64 different kinds of initial conditions. Then, according to chosen-ciphertext attack and divide-and-conquer attack, it is found that under the condition of selecting the ciphertext as zero, the original chaotic equation is degenerated as a linear one. So, by setting appropriate initial conditions, the secret keys (a) over cap (4i), (a) over cap (5i), (a) over cap (6i), (a) over cap (7i), (a) over cap (8i) (i = 4, 5, 6, 7, 8) can be deciphered with only four iterative operations. As for the secret keys a(4i), a(5i), a(6i), a(7i), a(8i) (i = 1, 2, 3) multiplied by ciphertext and the secret keys sigma(i), epsilon(i) (i = 1, 2, 3) related to nonlinear functions, maybe a more powerful attack method is required for these secret keys to be deciphered. Finally, an improved chaotic stream cipher scheme equipped with the low 8 bits derived from nonlinear operation of multiple state variables for encryption is proposed for improving the ability to resist divide-and-conquer attack and chosen-ciphertext attack. |
