Abstract The motivation for this article stems from the fact that medical image security is crucial maintaining patient confidentiality and protecting against unauthorized access or manipulation. This paper presents a novel encryption technique integrates Deep Convolutional Generative Adversarial Networks (DCGAN) Virtual Planet Domain (VPD) approach to enhance protection of images. method uses Learning (DL) framework generate decoy image, which forms basis generating keys using timestamp, nonce, 1-D Exponential Chebyshev map (1-DEC). Experimental results validate efficacy in safeguarding images various threats, including access, tampering, adversarial attacks. randomness encrypted are demonstrated through National Institute Standards Technology (NIST) SP 800-22 Statistical test suite provided Tables 4 14, respectively. robustness key sensitivity, noise, cropping attacks, attacks shown Figs. 15–18, 22–23, 24. data presented 5, 6, 7 shows proposed algorithm robust efficient terms time space complexity.

<p>The widespread use of computer hardware and software in society has led to the emergence a type criminal conduct known as cybercrime, which become major worldwide concern 21st century spanning multiple domains. As result, present setting, academics practitioners are showing great deal interest conducting research on cybercrime. In this work, fractional-order model was replaced by involving three sorts human populations: online users, hackers, cyber security professionals, order examine user-hacker system. The existence, uniqueness boundedness were studied. To support our theoretical conclusions, numerical analysis influence various logical parameters conducted we derived necessary conditions for different equilibrium points be locally stable. We examined effects fear level refuge factor densities prey predators explore understand dynamics system better way. Using some special circumstances, examined. Our findings validated through utilizing generalized Adams-Bashforth-Moulton technique.</p>

In view of the security problems image encryption algorithms encoded by single DNA or RNA, to increase randomness diffusion process and uncertainty coding rules, we propose a combining dynamic RNA computing based chaotic algorithm, which has more complicated for improving algorithm increases difficulty decoding. First, new three-dimensional hyperchaotic map is proposed, exhibits rich set behaviors. Second, sequences generated proposed are passed NIST test with good implemented digital signal processing hardware, shows feasibility industrial applications. K-means used split plaintext into two parts. Third, sequence displace diffuse parts plaintext, respectively. Then, were encode using these parts, compute Finally, cipher text decoded accordingly. The experimental results show that compared some related algorithms, our method higher security.
