Cryptanalysis of encryption scheme based on compound coupled logistic map and anti-codifying technique for secure data transmission

Abstract

The aim of this article is to provide cryptanalysis of chaos-based technique based on anti-codifying mechanism. The use of chaos in information security is deemed a secure trace of randomness. Many cryptosystems offer robust security against classical attacks having vulnerability in their structure. Recently, a compound coupled logistic chaotic map-based image encryption scheme was suggested. The encryption structure reveals some security flaws in the implementation. The original model includes input-independent swapping and substitution-based operations. In this work, we have intended a chosen-plaintext attack on a recently offered cryptosystem and suggested an anti-codifying technique for secure data transmission. The simulation and experimental outcomes reveal that the improvement suggestions can resist classical attacks.
