Early cancer identification is regarded as a challenging problem in cancer prevention for the
healthcare community. In addition, ensuring privacy-preserving healthcare data becomes …

In this paper, a new improved Lorenz system (ImproLS) is designed with a better behavior
due to a larger positive Lyapunov exponent. Then, an asymmetric image encryption scheme …

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 …

In this work, an efficient image encryption based on S-boxes and fractional-order logistic
map is proposed. The features of the fractional-order chaotic system in dynamical behaviors …

In this paper, a noise-resistant image encryption scheme is proposed. We have used a cubic-
logistic map, Discrete Wavelet Transform (DWT), and bit-plane extraction method to encrypt …

As the only nonlinear component, S-Box plays an important role in cryptography. To
overcome the problems in some 1D chaotic maps such as poor randomness and lacking …

A number of image encryption techniques have been proposed in recent years. These
techniques use either spatial or transform domain image processing. A major challenge …

The advancement in wireless communication has encouraged the process of data
transferring through the Internet. The process of data sharing via the Internet is prone to …

As the only nonlinear component for symmetric cryptography, S-Box plays an important role.
An S-Box may be vulnerable because of the existence of fixed point, reverse fixed point or …

In the symmetric key cryptography, the purpose of the substitution box is to generate
confusion and hence improve the security of the whole cryptosystem. For this reason, many …
