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 …

Many chaos-based hash functions have convoluted designs that are not based on proper
design principles, complicating the verification of security claims. We address this problem …

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 …

Applying the chaos theory for secure digital communications is promising and it is well
acknowledged that in such applications the underlying chaotic systems should be carefully …

Chaotic maps have various properties that mirror the security requirements of cryptographic
algorithms. As such, researchers have utilized them in the design of algorithms such as hash …

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 …

In this paper, we propose, implement, and analyze the structures of two keyed hash
functions using the Chaotic Neural Network (CNN). These structures are based on Sponge …

The chaotic maps posses high parameter sensitivity, random-like behavior and one-way
computations, which favor the construction of cryptographic hash functions. In this paper, we …

This paper proposes a new chaotic keyed hash function based on a single 4-dimensional
chaotic cat map whose irregular outputs are used to compute a hash value. The suggested …

In this paper, a new chaos-based hash function is proposed based on a recently proposed
structure known as the deterministic chaotic finite state automata (DCFSA). Out of its various …
