Eman M. Abou-Nassar,Abdullah M. Iliyasu,Passent El-Kafrawy,Oh-Young Song,Ali Kashif Bashir,Ahmed A. Abd El-Latif +5 more
TL;DR: A Blockchain Decentralised Interoperable Trust framework (DIT) for IoT zones where a smart contract guarantees authentication of budgets and Indirect Trust Inference System (ITIS) reduces semantic gaps and enhances trustworthy factor (TF) estimation via the network nodes and edges.
Journal ArticleDOI
Efficient cryptosystem approaches: S-boxes and permutation–substitution-based encryption
TL;DR: Two efficient cryptosystem schemes in the form of permutation–substitution based on chaotic systems have superior performance and great potential for prominent prevalence in cryptographic applications compared to previous schemes.
Journal ArticleDOI
Chaos-based partial image encryption scheme based on linear fractional and lifting wavelet transforms
TL;DR: A new chaos-based partial image encryption scheme based on Substitution-boxes (S-box) constructed by chaotic system and Linear Fractional Transform is proposed, which showed high performances and great potential for prominent prevalence in cryptographic applications.
Journal ArticleDOI

Nestor Tsafack,Jacques Kengne,Bassem Abd-El-Atty,Abdullah M. Iliyasu,Abdullah M. Iliyasu,Abdullah M. Iliyasu,Kaoru Hirota,Ahmed A. Abd El-Latif,Ahmed A. Abd El-Latif,Ahmed A. Abd El-Latif +9 more
TL;DR: Since the network is characterised by smooth fourth-order exponential nonlinearity, a distinctive approach is employed to assess its different properties: the circuit stability near fixed points is examined and dynamic complexity is evaluated using the Lyaponov spectrum analysis, bifurcation analysis and phase space trajectories.
