Nowadays, security in data transfer is of special importance. Images are of the most
attractive kinds of data in the encryption domain. Color images are more attractive than the …

Chaotic systems are suitable for image encryption owing to their numerous intrinsic
characteristics. However, chaotic maps and algorithmic structures employed in many …

For many years dissipative quantum maps were widely used as informative models of
quantum chaos. In this paper, a new scheme for generating good pseudo-random numbers …

In the last two decades, the use of chaotic iterative maps in cryptographic systems,
especially chaotic hash functions, has been expanding. Sensitivity to small changes in initial …

In order to overcome the disadvantages of logistic map in designing chaos-based cipher, the
piecewise logistic map (PLM) is presented. Some properties related to cryptography of the …

In recent years, a chaotic system is considered as an important pseudo-random source to
pseudo-random number generators (PRNGs). This paper proposes a PRNG based on a …

Chaotic hash functions are a prospective branch of modern cryptography. Being compared
with traditional hashing algorithms, an approach based on deterministic chaos allows …

The non-linear property of Chaos is a promising approach to information security, and many
accomplishments have been made by combining Chaos with several sub-security domains …

Secure hash functions play a fundamental role in cryptographic and Web applications. They
are mainly used, within digital signature schemes, to verify the integrity and authenticity of …

Cryptographic hash functions can map data of arbitrary size to data of fixed size (hash
values), which can be used in a wide range of multimedia applications for communication …
