The third party misuse and manipulation of digital images is a threat to security and privacy
of human subjects. The requirements to fulfil the security needs of digital images have led to …

In this paper, we introduce a novel color image encryption algorithm based on DNA
sequence operations, one-time keys and the spatiotemporal chaos. Firstly, the key streams …

To improve the randomicity behaviors of some existing chaotic maps, this paper proposes
two integrated chaotic systems (ICS), which conduct cascade, nonlinear combination, and …

Nowadays, many image cryptosystems have been cracked by chosen-plaintext attacks, for
they are not highly sensitive to plain image. To solve this problem, we introduce a plaintext …

Recently, an image encryption scheme based on a 2D hyperchaotic map is proposed. It
adopts the permutation–diffusion architecture and consists of three steps, which are …

The substitution box (S-box) is one of the extremely important components in the design of
block cipher. An excellent S-box is necessary for the block cipher algorithm, and its cipher …

Control parameters play a key role in a chaotic system, where they directly determine its
chaotic performance. In this brief, we propose a novel parameter-selection-based chaotic …

In this study, a novel cryptographic model that uses coupled map lattice is proposed for
securing image. It incorporates mixing based on randomly generated secret key, sub-keys …

In order to effectively resist the plaintext attacks introduced in recent cryptanalysis literatures,
a reformative image encryption algorithm based on discrete logarithm and a memristive …

In this paper, the security performance for an 8D self-synchronous and feedback-based
chaotic stream cipher with the low 8 bits of state variables for encryption is analyzed …
