An Image Encryption Scheme Based on Chaotic Systems

Xiao, Huang-pei, Zhang, Guo-ji·2006·2006 International Conference on Machine Learning and Cybernetics

Abstract

An image encryption scheme based on chaotic systems is proposed in this paper. By combining the spatial-domain encryption of digital images and the traditional stream ciphers technology, the security of the encryption scheme is enhanced effectively. Instead of encrypting an image in a chaotic signal directly, the proposed scheme uses two chaotic systems based on the thought of higher secrecy of multi-system. One of the chaotic systems is used to generate a chaotic sequence. Then this chaotic sequence is transformed into a binary stream by a threshold function. The other chaotic system is used to construct a permutation matrix. Firstly, the pixel values of a plain image are modified randomly using the binary stream as a key stream. Secondly, the modified image is encrypted again by permutation matrix. The security of encryption scheme is analyzed in detail. And the simulation results show that the proposed scheme has a better efficiency than others' and a high security performance

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The probability density function of the logistic map is not uniform, but by introducing a proper threshold level, the output bit sequence becomes uniform.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
