LSD and Anukul: An account of what it feels like to live in the early 21st century Keywords: Cinema, Digital technology, Affect Vivian Sobchack suggests in talking about post-cinema, “Insofar as the photographic, the cinematic, and the electronic have each been objectively constituted as a new and discrete techno-logic, each also has been subjectively incorporated, enabling a new and discrete perceptual mode of existential and embodied presence.” That is to say, as they have mediated and represented our engagement with the world, with others, and with ourselves, photographic, cinematic, and electronic technologies have transformed us so that we presently see, sense, and make sense of ourselves as quite other than we were before each of them existed. This paper shall look at the particular articulation of this formation of a self in a digital culture of cinema and cinema-like technologies. It shall consider two films – short Anukul (Sujoy Ghosh, 2017) and Love, Sex aur Dhokha (Dibakar Banerjee, 2010) to suggest that digital technologies of cultural production create affective maps. These film and video works are expressive: in the ways that they give voice (give sounds and images) to a kind of ambient, free-floating sensibility that permeates our society today, although it cannot be attributed to any subject in particular. The digital then in these instances, lies at the very heart of social production, circulation, and distribution. It generates subjectivity, and plays a crucial role in the valorization of capital.

Abstract

The possibility of a quantum system to exhibit properties that are akin to both the classically held notions of being a particle and a wave, is one of the most intriguing aspects of the quantum description of nature. These aspects have been instrumental in understanding paradigmatic natural phenomena as well as to provide non-classical applications. A conceptual foundation for the wave nature of a quantum state has recently been presented, through the notion of quantum coherence. We introduce here a parallel notion for the particle nature of a quantum state of an arbitrary physical system. We provide elements of a resource theory of particleness, and give a quantification of the same. Finally, we provide evidence for a complementarity between the particleness thus introduced, and the coherence of an arbitrary quantum state.

Abstract

In today’s digital age, access to knowledge and information is crucial for societal growth. Although widespread resources like Wikipedia exist, there is still a linguistic barrier to breakdown for low-resource languages. In India, millions of individuals still lack access to reliable information from Wikipedia because they are only proficient in their regional language. To address this gap, our work focuses on enhancing the content and digital footprint of multiple Indian languages. The primary objective of our work is to improve knowledge accessibility by generating a substantial volume of high-quality Wikipedia articles in Telugu, a widely spoken language in India with around 95.7 million native speakers. Our work aims to create Wikipedia articles and also ensures that each article meets necessary quality standards such as a minimum word count, inclusion of images for reference, and an infobox. Our work also adheres to the five core principles of Wikipedia. We streamline our article generation process, leveraging NLP techniques such as translation, transliteration, and template generation and incorporating human intervention when necessary. Our contribution is a collection of 8,929 articles in the movie domain, now ready to be published on Telugu Wikipedia.

Abstract

Air Smart Vehicular Networks (ASVNs) have become increasingly essentials in military and commercial industries in recent years, where drones are deployed to interact among each other via wireless medium in airspace due to their agility and versatility. ASVNs can form a closed loop from data perception to final execution by integrating communication devices, computation tools, and control modules. However, the used unencrypted and publicly available navigational signals like Global Positioning System (GPS) and communication over (public) insecure Internet connections, including wireless networks and WiFi, make ASVNs vulnerable to security breaches. Attackers can easily gain access to a drone's configuration and take control remotely, by launching various attacks such as GPS spoofing, false sensor data injection, maldrone malware injection, eavesdropping, man-in-the-middle, Denial-of-Service (DoS), replay, forgery, and Skyjack attacks. This paper proposes a robust and efficient multi-factor biometric-based security mechanism using blockchain as a service to address the security and privacy breaches in ASVNs. A comparative study demonstrates that the proposed scheme provides superior security and better functionality features with low communication and computation overheads as compared to the existing analogous schemes. The feasibility of the proposed scheme in real-life drone applications is also demonstrated through a real-time testbed and blockchain simulation. Furthermore, a detailed security analysis using the automated software validation tool, namely Scyther, verifies the proposed scheme's significant level of security

Abstract

Owing to the growth of the intelligent Internet of Vehicles (IoV), the notion of the Social Internet of Vehicles (SIoV) has emerged. SIoV is based on the intelligent IoV combined with social needs, and it uses existing vehicle self-organizing network technologies to enable in-vehicle social networking platforms. The rapid development of the Internet of Things (IoT) has led to an explosion in the number of in-vehicle electronic devices, external facilities, vehicles, and a massive amount of real-time data generated by these vehicles, devices, drivers, passengers, and other social relationships. This explosion has put tremendous load pressure on servers; hence, researchers have started to apply fog computing to SIoV to spread server overload. However, there are still a number of risks and challenges associated with SIoV. Therefore, we propose an authentication scheme for fog computing-enabled SIoV that guarantees user anonymity and security. Detailed security analysis proves that the proposed scheme can secure against known attacks. Finally, we evaluate the performance of our scheme, and the results show that it has excellent security, computation, and communication performances.

Abstract

The key factor accelerating the development of intelligent transportation and reduced traffic congestion is the vehicle ad hoc network (VANET). However, the swift upsurge in the diversity of vehicles puts the development of the vehicle network's safety system through plentiful glitches. To receive the messages promptly, attain the confidentiality of vehicle identity, and authentication swiftly in VANET, we present a new identity-based aggregate signature (IBAGS) system using the lattices. The proposed lattice-based method presented in this article combines the batch verification and aggregate signature scheme (ASS), which finishes the authentication of several vehicular units and aggregates multiple users' signatures into a single (compact) signature. This boosts the competence of the verification process. Furthermore, the vehicle pseudo-identities are also utilized to meet the goals of vehicle identity and privacy protection. Finally, dependable cloud storage technology efficiently enables the secure storing of message signatures. This article demonstrates the lower storage overhead and increases authentication efficiency while maintaining security compared to similar competing schemes.

Abstract

The rise of smart cities is directly connected to the increasing use of vehicles. The growing vehicle utilization has driven the emergence of Vehicular Ad-hoc Networks (VANETs), facilitating instant information exchange among vehicles. The system provides essential information regarding road conditions, traffic patterns, and more relevant data. VANETs encompass two fundamental categories of communication exchanges, namely Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I). V2I technology facilitates the integration of cars and transportation infrastructure, enabling effective communication between vehicles and infrastructure. Nevertheless, the potential of V2I communication has various security concerns arising from prevalent security threats. Current authentication techniques encounter challenges regarding complexity, security, and privacy considerations. We designed a hash-based lightweight and anonymous authentication scheme to address the aforementioned restrictions and enhance the effectiveness of authentication in V2I architecture. This scheme effectively combines identity, password, and bio-metric to enhance resistance against impersonation, denial of service, and privileged insider attacks. The devised scheme distinguishes itself by a comparative analysis and security proofs, highlighting its superior capability in guaranteeing secure authentication in V2I communication. The comprehensive security analysis conducted formally and informally showcases the robustness of the proposed solution against several threats. The performance evaluation results show that our scheme demonstrates a decrease in the computational cost of 51.40% approximately and a reduction in communication overhead of around 22.57%. These results establish the efficiency and scalability of the proposed scheme as a viable solution for V2I architecture.

Abstract

The Internet of Nano Things (IoNT) is increasingly recognized as a superior alternative to the Internet of Things (IoT) due to its inherent benefits. However, the security of IoNT remains an open challenge that needs to be addressed at various levels. Given the highly sensitive data shared in IoNT, the development of security protocols becomes imperative. Despite the emergence of some methodologies, many security aspects have been overlooked, and no concrete cryptosystems have been developed. In this paper, we propose an Identity-Based Encryption (IBE) scheme built on the Learning With Errors (LWE) assumption. We design a lightweight protocol with the consideration of resource-constrained devices involved in the IoNT network. The proposed scheme is resistant to various attacks, including side-channel analysis, replay attacks, man-in-the-middle attacks, plaintext and ciphertext attacks, ensuring unforgeability. Additionally, performance evaluation indicates that the proposed scheme outperforms existing ones in terms of computational and communication costs.

Abstract

6G (sixth-generation wireless), the successor to 5G cellular technology, operates at higher frequencies than its predecessor and supports significantly greater capacity and markedly reduced latency. Healthcare is treated as a complex system with various stakeholders, like doctors, patients, hospitals, pharmaceutical companies as well as healthcare decision-makers. The innovations in the Internet of Things (IoT) and incorporating emerging technology in the healthcare systems provide the quality of services to the people and save millions of lives. However, patient privacy and secure interchange of medical data from various healthcare providers need to be adequately addressed. Furthermore, incorporating blockchain in the healthcare system helps to make the system more transparent and secure due to inherent properties of the blockchain. In addition, Big Data analytics helps in analyzing large datasets from hundreds of patients, and then in identifying various clusters and correlation among datasets, and also in developing predictive models. In this paper, we aim to propose a new smart contract-based access control for 6G-enabled blockchain assisted in the healthcare system (in short, we call it as SACS). SACS provides a patient to communicate with its healthcare management authority securely and helps to interchange his/her medical information across healthcare providers. A detailed security analysis, experimental results and comparative study assure that the proposed SACS is secure by preventing possible active and passive attacks, andrequires less computational and communication costs as compared to those for other relevant competing schemes.

Abstract

The next generation of Quantum Internet of Things (QIoT) has the potential to revolutionize various sectors, including smart homes, health-care, and smart cities, by enabling more sophisticated and interconnected systems. These applications incorporate advanced features, such as autonomous decision-making based on Quantum Artificial Intelligence and Machine Learning (QAI/ML) and context-aware functionality. The security of the data in these applications relies on traditional cryptographic techniques, which, however, face a growing threat due to the significant advancements in quantum computing, especially with the Shor's algorithm. This algorithm poses a substantial risk of breaking conventional cryptographic methods within a feasible timeframe. To address these emerging security challenges in the quantum realm, we propose a Quantum Key Distribution (QKD) based on the BB84 protocol. This approach aims to provide robust authentication using certificates through a classical channel and secure quantum key exchange via a quantum channel in a public environment. The proposed QKD scheme is implemented using a client-server model in Python and Qiskit, demonstrating its practicality in real-world applications. The obtained results showcase the successful establishment of a secure session key between IoT smart (sensor) devices and gateway nodes, effectively mitigating potential threats such as eavesdropping.
