This paper proposes a new chaotic system based on two parameters. The proposed chaotic
system has good chaotic characteristics, and it can be shown that the chaotic system is …

Chaotic systems are widely used in image encryption due to their sensitivity to initial values,
ergodicity, and other properties; many image encryption algorithms based on chaotic …

In modern-day block ciphers, the role of substitution-boxes is to transform the plaintext data
nonlinearly to generate ciphertext data with sufficient confusion. It has been well-confirmed …

As digital products communicate over public networks, digital image security becomes
essential. Despite advancements in encryption technology, protecting data from secure …

A new n-dimensional conservative chaotic model is proposed to quickly realise a
conservative chaotic system. The validity of this model is verified by generating a five …
