“…They can provide richer dynamics, increasing the difficulty for attackers to predict the system's state. Some scholars have explored five or higher-dimensional chaotic systems 18 – 20 , where computational complexity grows exponentially with dimensionality. This may lead to a significant reduction in the real-time performance of image encryption in resource-constrained environments, such as embedded systems or mobile devices.…”

To enhance the security of image data transmission, and address the weaknesses of existing image encryption schemes based on chaotic systems, particularly concerning resistance to differential attacks and the unstable performance of chaotic systems, this article introduces an improved four-dimensional chaotic system and integrates evolutionary operators to propose an image encryption scheme. Firstly, a method for generating pseudo-random sequences associated with the plaintext is designed. The change rate of the ciphertext pixel value exceeds 0.9967 after a slight modification of the plaintext pixel value, significantly improving the plaintext sensitivity and the scheme's ability to resist selected plaintext attacks. Secondly, an individual rearrangement operation is introduced to achieve bit-level scrambling, and pixel-level scrambling is achieved by selection strategy. Subsequently, crossover and mutation operations are incorporated into image encryption. To reflect the randomness of the pairing, we adopt the pseudo-random sequence generated by the chaotic system to control the crossover and mutation operators, and a diffusion operation is performed on selected pixel pairs. Finally, ciphertext feedback is applied. Experimental results and performance analysis demonstrate that the proposed scheme not only enhances the security of encrypted images but also effectively resists noise and cropping attacks. This method effectively meets the high-security requirements of images in network transmission and provides new ideas for further research in the field of image encryption.

“…Nowadays, cities face various challenges, including aligning urban development with sustainability and resilience while reducing the carbon footprint. Integrating innovative solutions underpins the "Smart City" concept and includes state-of-the-art technologies such as information and communication technology, the Internet of Things, and 5G networks [1]. One critical issue arises regarding the efficacy of these new technologies and interventions in effectively addressing the urban development paradigms and with the development of service science since 2008, positing that an effective smart city should embrace a service-oriented paradigm that not only considers technological and innovative aspects but also underscores the intrinsic value and value co-creation among citizens and diverse stakeholders [2].…”

This paper investigates the significance of context comprehension within the smart city domain by emphasizing the various perspectives of stakeholders such as ministries, municipalities, and citizens. Since the value of service provision depends on the interactions across different service systems within distinct domains and contexts, through an exploration of the value chain and formulation of value propositions, the paper aims to achieve the synergy among diverse service contexts. Using the smart city context of the Czech Republic as a case study, the paper systematically examines the implementation of context-driven methodology and provides insights for the broader development of smart cities. Also, this study highlights the importance of understanding service overlaps and identifies key issues for future service research, with potential applicability in smart city initiatives, particularly in middle and eastern EU countries.

Aim To develop and apply advanced methods to enhance medical image security, ensuring patient data integrity, confidentiality, and authenticity throughout the stages of image collection, transmission, and storage. Background Retaining patient privacy and data accuracy in the context of accessible healthcare require the secure broadcast and storage space of medical imaging. Because of the increasing dependence on digital medical imaging technology, it is essential to protect these private images from illegal access and possible cyber attacks. Objective Work addresses the drawbacks of conventional encryption techniques in the healthcare sector and offers a novel Crypto-Aware Elliptic Curve Diffie Hellman with Key Derivation Function (CAECDH-KDF) encryption technique to improve the security of medical images. Methods The suggested encryption architecture combine domain-specific methods designed for medical imaging data with sophisticated cryptographic algorithms. The framework, in difference to conservative encryption methods, employs an effective tactic that strikes a compromise between processing speed and security. To achieve this, better encryption methods for medical image characteristics are incorporated. Results Comparisons are made between the suggested method's security, computation time (0.003001), encryption time (0.001998s), decryption time (0.001001s), entropy (7.997633), and throughput (4.0887) of conventionally encrypted approaches. Conclusion A large amount of test images have been utilized to evaluate the effectiveness of the suggested technique. According to numerous tests, the suggested strategy outperforms conventional methods.
