Presenting encryption algorithms with diverse characteristics, Image Encryption: A
Communication Perspective examines image encryption algorithms for the purpose of …

In recent years, a growing number of cryptosystems based on chaos have been proposed,
many of them fundamentally flawed by a lack of robustness and security. In this Letter, we …

In 1998, MS Baptista proposed a chaotic cryptosystem, which has attracted much attention
from the chaotic cryptography community: some of its modifications and also attacks have …

Since 1980s, the idea of using digital chaotic systems to design new ciphers has attracted
more and more attention. The use of chaos in cryptography depends on the natural relation …

In recent years many chaotic cryptosystems based on Baptista's seminal work have been
proposed. We analyze the security of two of the newest and most interesting ones, which …

Recently two encryption schemes were proposed by combining circular bit shift and XOR
operations, under the control of a pseudorandom bit sequence (PRBS) generated from a …

In this article, an improved Lorenz system was constructed, in the first stage, a nonlinear
term in general Lorenz system was replaced by the sum of term of exponential function and …

In this paper, the peculiarities of a quadratic map are investigated, unveiling the hidden
relationship with the classical logistic map. Moreover, the improvements in generating odd …

In recent years, chaotic systems have surfaced to become an important field in
steganographic matters. In this paper, we present a simple cryptic-free least significant bits …
