Breaking a new substitution-diffusion based image cipher using chaotic standard and logistic maps

TL;DR

This paper demonstrates that an image encryption scheme based on chaotic standard and logistic maps is vulnerable and can be compromised with a single chosen plaintext, revealing significant security flaws.

Contribution

It provides a security analysis showing the scheme can be broken with minimal effort and identifies additional security weaknesses.

Findings

The scheme can be broken with one chosen plaintext.

Several security defects are identified.

The encryption scheme is insecure against known attacks.

Abstract

Recently, an image encryption scheme based on chaotic standard and logistic maps was proposed. This paper studies the security of the scheme and shows that it can be broken with only one chosen-plaintext. Some other security defects of the scheme are also reported.
