This paper proposes a lightweight image encryption scheme that is based on 3 stages. The
first stage incorporates the use of the Rössler attractor for the Rössler system, the second …

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 …

The need for image encryption schemes that are of low computation complexity is ever
increasing. Meanwhile, the use of chaotic functions and mathematical sequences to …

Symmetric encryption has been considered as one of the essential means of ensuring
security of end to end communication. The robustness and strength of modern day block …
