A new color image encryption algorithm is proposed by using chaotic maps. Cipher image is
constructed in three phases. In the first phase permutation of digital image is performed with …

Cryptography is commonly used to secure communication and data transmission over
insecure networks through the use of cryptosystems. A cryptosystem is a set of cryptographic …

Many cryptographic protocol have been realized using similarities between chaos and
cryptology. One of the most successful examples of these protocols has been s-box …

Achieving proper nonlinear properties and autocorrelation in the S-box structure is an open
challenge in cryptography. Besides, there have been numerous articles on the optimization …
