Cryptanalysis of an image encryption scheme based on a new total shuffling algorithm

TL;DR

This paper analyzes recent image encryption schemes based on chaotic systems, revealing vulnerabilities through a chosen-plaintext attack and demonstrating how to compromise their security.

Contribution

It identifies security flaws in new chaotic image encryption schemes and demonstrates effective cryptanalysis methods to break them.

Findings

The schemes are vulnerable to chosen-plaintext attacks.

Security flaws are linked to the permutation and XOR operations.

Cryptanalysis can successfully recover original images.

Abstract

Chaotic systems have been broadly exploited through the last two decades to build encryption methods. Recently, two new image encryption schemes have been proposed, where the encryption process involves a permutation operation and an XOR-like transformation of the shuffled pixels, which are controlled by three chaotic systems. This paper discusses some defects of the schemes and how to break them with a chosen-plaintext attack.
