This paper proposes a novel five-dimensional (5D) memristor-based chaotic system by introducing flux-controlled memristor into 3D with two stable equilibrium points, and increases the dimensionality utilizing state feedback control method. The newly proposed has line so corresponding attractor belongs to hidden attractor. By using typical nonlinear analysis tools, complicated dynamical behaviors of new are explored, which reveals many interesting phenomena, including extreme homogeneous heterogeneous multistabilities, transient transition behavior, offset-boosting control. Meanwhile, unstable periodic orbits embedded in were calculated variational method, pruning rules summarized. Furthermore, analog DSP circuit implementation illustrates flexibility memristic system. Finally, active synchronization was investigated, demonstrating important engineering application values

Memristive technology mitigates the memory wall issue in von Neumann architectures by enabling in-memory data processing. Unlike traditional complementary metal-oxide semiconductor (CMOS) technology, memristors provide a new paradigm for implementing cryptographic functions and security considerations. While prior research explores side-channel attack vulnerabilities, our study uniquely addresses memristor-oriented countermeasures. We review different memristive crossbar configurations, implement four-bit S-box function, analyse hiding masking techniques using self-rectifying passive crossbar. Our findings confirm efficacy of but highlight limitations masked dual-rail pre-charge logic (MDPL) methods. Effective MDPL depends on specific power consumption conditions, i.e. profile input ‘01’ ‘10’ are not clearly distinguishable from ‘00’ ‘11’, which, however, satisfied across various families. Despite passing t -tests, xor4Sbox with CRS-based failed stochastic approaches owing to differences. prioritizes countermeasures, advancing understanding challenges opportunities functions.

In the healthcare sector, e-diagnosis through medical images is essential in a multi-speciality hospital; securing becomes crucial for preserving an individual's privacy e-healthcare applications. So, this paper has proposed novel encryption scheme implemented on reconfigurable hardware. Realising image schemes FPGA hardware platforms offers substantial advantages over software implementations. The image-specific key and Hopfield Neural Network (HNN) carry out diffusion process using suggested method. confusion accomplished simultaneously by pseudo-random memory addresses derived via 16-bit stream cipher circuit, which incorporates cryptography neural network dynamics methods. By breaking up spatial redundancy data, mechanism increases data's resilience against statistical attacks, yielding average entropy of 7.99 near zero correlation. When platform, dual-layer technique's fast processing speed, parallelism, reconfigurability are benefits, especially real-time resource-constrained implementation occupies 20% total 424.71 mW power dissipation Intel Cyclone V FPGA.

Locally active memristors with an Edge-of-Chaos kernel (EOCK) represent a significant advancement in the simulation of neuromorphic dynamics. However, current research on EOCK remains at circuit level, without further analysis their feasibility. In this context, we designed memristor and installed it third-order circuit, where showed local activity stability under defined voltage inductance parameters. This behavior ensured that by varying input inductance, could effectively simulate various neural activities, including inhibitory postsynaptic potential chaotic waveforms. By subsequently integrating into Hopfield network (HNN) framework substituting self-coupling weight, observed rich spectrum dynamic behaviors, rare phenomenon antimonotonicity bubble bifurcation. Finally, used hardware circuits to realize these generated phenomena, confirming feasibility memristor. introducing HNN studying its implementation, study provides theoretical insights empirical basis for developing systems replicate complexity human brain functions. reference development application future.
