Chaos has been one of the most effective cryptographic sources since it was first used in
image-encryption algorithms. This paper closely examines the development process of …

Recently, many researchers have been interested in the application of chaos in
cryptography. Specifically, numerous research works have been focusing on chaotic image …

Owing to the incremental and diverse applications of cryptocurrencies and the continuous
development of distributed system technology, blockchain has been broadly used in fintech …

This paper proposes a high-quality color image compression-encryption scheme based on
chaos and block permutation. In this scheme, the color digital image is first converted and …

In traditional compressed sensing (CS), the measurement matrix always faces problems
such as large data storage, high memory usage and a large amount of data calculation. To …

Image encryption schemes can be vulnerable to a variety of cryptanalysis attacks. The use of
key-dependent dynamic S-boxes has been shown to improve security. Threats of chosen …

Many researchers have used the properties of the popular Elliptic Curve Cryptography
(ECC) to devise a stronger and faster image encryption algorithm to assure the secrecy of …

Image steganography is a technology that hides sensitive information into an image. The
traditional image steganography method tends to securely embed secret information in the …

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 …

Images contain very sensitive and confidential information. Because images play a
significant role in many applications such as military communication, remote‐sensing, and …
