Depreciating motivation and empirical security analysis of chaos-based image and video encryption

Abstract

Over the past years, an enormous variety of different chaos-based image and video encryption algorithms have been proposed and published. While any algorithm published undergoes some more or less strict experimental security analysis, many of those schemes are being broken in subsequent publications. In this paper, we show that two main motivations for preferring chaos-based image encryption over classical strong cryptographic encryption, namely computational effort and security benefits, are highly questionable. We demonstrate that several statistical tests, commonly used to assess the security of chaos-based encryption schemes, are insufficient metrics for security analysis. We do this experimentally by constructing obviously insecure encryption schemes and demonstrating that they perform well and/or pass several of these tests. In conclusion, these tests can only give a necessary, but by no means a sufficient condition for security. As a consequence of this paper, several security analyses in related work are questionable; further, methodologies for the security assessment for chaos based encryption schemes need to be entirely reconsidered.

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 security assessment metrics used in chaotic cryptography are far ineffective for security analysis.

    “Considering the quantitative test results of the four special schemes on the metrics, it is concluded that the metrics are far ineffective for security analysis”
  • In [116], four obviously insecure encryption schemes were constructed to question the credibility of widely used security assessment metrics in chaotic cryptography.

    “In [116], four obviously insecure encryption schemes are subtly constructed to question credibility of the security assessment metrics used in the field of chaotic cryptography widely”
  • The most striking image cryptanalysis work in 2018 is [116], which refutes any superiority of chaos-based encryption schemes over several variants of AES in computational effort and security performance.

    “Among them, the most striking work is depreciating motivation of most chaos-based encryption schemes in [116], refuting any superiority of chaos-based encryption schemes than several variants of AES in terms of computational effort and security performance”
  • The security assessment metrics used in most chaos-based image encryption schemes are unconvincing.

    “As shown in [116,117], the security assessment metrics used in most chaos-based image encryption schemes are unconvincing.”
  • The security test metrics are widely misused in image encryption schemes.

    “The security test metrics are widely misused.”

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.
