Improved Shimizu-Morioka system and its application in image encryption
This work presents a memristive Shimizu-Morioka system (MSMS) constructed by integrating a universal voltage-controlled memristor model into the Shimizu-Morioka system. The regulatory mechanisms of parameter variations on state transitions and dynamic characteristics are elucidated through theoretical analysis. The results demonstrate that the MSMS exhibits constant Lyapunov exponents with respect to the memristive parameter, enabling flexible amplitude modulation of chaotic signals. NIST tests confirm that the chaotic sequences generated by the MSMS meet cryptographic standards. Multisim circuit simulations verify the system's engineering feasibility. Furthermore, the chaotic sequences are successfully applied to a novel image encryption scheme, validated through security analyses including key sensitivity, statistical attack resistance, anti-cropping, anti-noise performance and anti-differential attacks. This study bridges chaos theory with practical cryptographic applications, offering a foundation for advancing chaos-based secure communication and encryption technologies.
期刊介绍:
Integration''s aim is to cover every aspect of the VLSI area, with an emphasis on cross-fertilization between various fields of science, and the design, verification, test and applications of integrated circuits and systems, as well as closely related topics in process and device technologies. Individual issues will feature peer-reviewed tutorials and articles as well as reviews of recent publications. The intended coverage of the journal can be assessed by examining the following (non-exclusive) list of topics:
Specification methods and languages; Analog/Digital Integrated Circuits and Systems; VLSI architectures; Algorithms, methods and tools for modeling, simulation, synthesis and verification of integrated circuits and systems of any complexity; Embedded systems; High-level synthesis for VLSI systems; Logic synthesis and finite automata; Testing, design-for-test and test generation algorithms; Physical design; Formal verification; Algorithms implemented in VLSI systems; Systems engineering; Heterogeneous systems.
