Applied Sciences (Switzerland), 2021 In cryptography, the pseudorandom number sequences must have random appearance to be used in secure information systems. The skew tent map (STM) is an attractive map to produce pseudorandom sequences due to its easy implementation and the absence of ...

Improved security analysis for OMAC as a pseudorandom function
Journal of Mathematical Cryptology, 2009 This paper shows that the advantage of any q-query adversary (which makes at most q queries) for distinguishing OMAC from a uniform random function is roughly Lq2/2n.

A pseudorandom bit generator based on hyperbolic cosine function [PDF]
ITM Web of Conferences, 2022 In the literature, little attention is paid to devising and analyzing novel one dimensional chaotic mappings. In our previous efforts, we have tried fold, translation & scale on arctangent function & sigmoid function respectively, which brings good ...

Lattice‐based nominative signature using pseudorandom function
IET Information Security, 2021 A nominative signature (NS) is a cryptographic primitive where two parties collude to produce a signature. It is a user certification system and has applications in a variety of sectors where nominee cannot trust heavily on the nominator to validate the ...

On the Use of Memristive Hyperchaotic System to Design Color Image Encryption Scheme
IEEE Access, 2020 In this article a novel encryption scheme based on memristive hyperchaotic system was proposed. Firstly, combined with SHA-512 hash function and plain image, key sequences can be generated by iterating the memristive hyperchaotic system.

Designing a Pseudo-Random Bit Generator Using Generalized Cascade Fractal Function
Chaos Theory and Applications, 2021 A cascade function is designed by combining two seed maps that resultantly has more parameters, high complexity, randomness, and more unpredictable behavior. In the paper, a cascade fractal function, i.e.
