Quantum computing poses a fundamental threat to the classical cryptographic mechanisms that underpin contemporary cloud security, motivating an urgent transition toward post-quantum solutions. This study introduces Quantum-Lattice Synergy (QLS), a next-generation security blueprint that integrates the computational hardness of lattice-based cryptography with the information-theoretic guarantees of quantum cryptographic primitives. QLS is a mix of Learning with Errors (LWE)-based encryption, quantum key distribution (QKD), and quantum-generated randomness to offer robust and scalable with resilience to future protection of cloud infrastructures. The architecture consists of three modules which are closely interrelated, namely, QLS-KG to generate quantum-lattice hybrid keys, QLS-Enc for lattice-based encryption with quantum-derived keys, and QLS-Auth to achieve secure authentication with quantum hashing and lattice trapdoors. Through rigorous mathematical modelling, security proofs and complexity analysis, it has been demonstrated that QLS provides a dual-layered defence which provides, at the computational level, computational security based on hard lattice problems, and at the physical level, physical security based on quantum mechanics. It has been experimentally shown that QLS is more efficient in key generation, encryption, and decryption compared to the state-of-the-art post-quantum protocols, such as LWE-based encryption, NTRU Encrypt, and Kyber512, depending on the quantum-assisted keying and parameterizing lattices, and achieving the same level of classical symmetric-key security at 256 bits. This characterization of security is not intended to mean an AES-256 baseline or to exclude the ability of existent schemes to meet similar security levels in the right configurations, it simply indicates that QLS has a strength in its hybrid, defence-in-depth architecture. QLS is created in a way that it can be deployed in the context of existing cloud facilities, which tackles durability of confidentiality, future economics, scalability and reliability of trust during the post-quantum era.
The research aims to identify the main artistic techniques used in contemporary film poster design, their typological features, and the patterns of their functioning within a multimedia environment, as well as to systematize modern forms of film posters. The article analyzes the current state of the film poster genre, considering technological and communicative changes, identifies key trends influencing its evolution, and proposes a classification of new film poster forms in the digital space. The scientific novelty of the study lies in identifying key technological and aesthetic trends that define the genre’s evolution in the digital age; in comprehensively systematizing multimedia forms of film posters; and in developing a typology of contemporary film posters based on their functional and format features. The research findings establish that the modern film poster is not merely a film announcement but a dynamic structure where technology blurs the boundaries between advertising, art, and interactive experience. Furthermore, an analysis of international projects has shown that the film poster has become a multifunctional communication tool whose effectiveness is determined not only by its reach but also by the depth of emotional interaction with the audience.
BackgroundTraditional vehicle-repairing carts in India present ergonomic challenges and occupational health and safety issues. Operators experience discomfort and strain due to difficulties in pushing the cart over long distances and in organising tools and setting up workstations.ObjectivesTo redesign the makeshift vehicle repairing cart by incorporating ergonomic principles and relevant anthropometric data of target users, aiming to reduce physical fatigue and improve usability.MethodsErgonomic evaluations were conducted to identify areas of discomfort, focussing on body parts affected. The operators expressed postural discomfort in different parts of the body like the lower back, neck, shoulder, forearm, wrist, ankle, and foot.ResultsResearchers made recommendations for the proper layout of the tools, provision for manipulating the vehicle in a better manner with ergonomically designed handles, and provision of a modular workstation detachable from the main unit. Accordingly, three concept prototypes were suggested.ConclusionThe manufacturer adopted all three concepts in principle for the new design to improve ergonomics and design of cart for user comfort.
Quantum key distribution (QKD) entanglement-based solutions have become effective solutions for providing security to communications owing to the increased challenges posed by quantum computing. Entanglement-based QKD protocols are especially suitable for deployment over existing metropolitan optical fibre infrastructure, particularly those that provide device-independent security. Nonetheless, their implementation is strongly hindered by environmental noise, decoherence by optical fibres, and interference by co-existent classical data traffic. This research paper provides an overall experimental report on the noise resistance of entanglement-based QKD, in this case, the BBM92 protocol of a metropolitan fibre network. To solve practical problems, this study presents a hybrid model with three adaptive algorithms: the Adaptive entanglement purification protocol (AEPP), noise-resilient key reconciliation algorithm (NRKRA), and optimised privacy amplification technique (OPAT). The AEPP constantly checks the entanglement fidelity and enhances it through the purification of pairs of photons, depending on the real-time channel conditions. The NRKRA builds upon efficient key reconciliation by dynamically using error correction coded to optimise the observed quantum bit error rate (QBER). OPAT also enhances system security because it can handle privacy amplification based on the degree of information leakage. Experimental findings indicate that such a combined method is able to produce low QBER, high secret key rates with improved entanglement fidelity, even in the fibre links of up to 50 km length and in the presence of environmental experiments. This work has shown that an adaptable and resilient structure of this kind goes far beyond the conceptual frameworks of QKD modelling and real-world applications to provide insights on the necessary performance standards and to provide viable implementation guidelines to large-scale quantum cryptographic systems in the future.
Global challenges such as environmental pollution, resource depletion, climate change, and loss of biodiversity, compounded by issues prevalent in third-world countries like overcrowded urban spaces and public health disparities, demand innovative, sustainable solutions. In response, this paper explores the integration of nature-inspired design and sustainability principles into interdisciplinary design education. The primary objectives are to develop an education framework that embeds these principles, fosters collaborative learning across disciplines, and equips students with the skills necessary to address both global and local sustainability challenges. As an initial approach subject of “Materials Exploration” is reframed using a workshop model based on Kolb’s experiential learning theory, emphasizing systems thinking and ecological impact. This model demonstrates how content can be transformed to foster a deeper understanding of nature-inspired principles and sustainable practices. The outcomes of this approach will guide the broader restructuring of design curricula, categorizing subjects according to their potential for sustainability integration. This paper thereby argues that interdisciplinary design education, with the core of biomimicry and sustainability, can produce a generation of designers capable of addressing contemporary global challenges through innovative, ethical, and sustainable solutions.
