Hash-Chain Fog/Edge: A Mode-Based Hash-Chain for Secured Mutual Authentication Protocol Using Zero-Knowledge Proofs in Fog/Edge

Authentication is essential for the prevention of various types of attacks in fog/edge computing. Therefore, a novel mode-based hash chain for secure mutual authentication is necessary to address the Internet of Things (IoT) devices’ vulnerability, as there have been several years of growing concerns regarding their security. Therefore, a novel model is designed that is stronger and effective against any kind of unauthorized attack, as IoT devices’ vulnerability is on the rise due to the mass production of IoT devices (embedded processors, camera, sensors, etc.), which ignore the basic security requirements (passwords, secure communication), making them vulnerable and easily accessible. Furthermore, crackable passwords indicate that the security measures taken are insufficient. As per the recent studies, several applications regarding its requirements are the IoT distributed denial of service attack (IDDOS), micro-cloud, secure university, Secure Industry 4.0, secure government, secure country, etc. The problem statement is formulated as the “design and implementation of dynamically interconnecting fog servers and edge devices using the mode-based hash chain for secure mutual authentication protocol”, which is stated to be an NP-complete problem. The hash-chain fog/edge implementation using timestamps, mode-based hash chaining, the zero-knowledge proof property, a distributed database/blockchain, and cryptography techniques can be utilized to establish the connection of smart devices in large numbers securely. The hash-chain fog/edge uses blockchain for identity management only, which is used to store the public keys in distributed ledger form, and all these keys are immutable. In addition, it has no overhead and is highly secure as it performs fewer calculations and requires minimum infrastructure. Therefore, we designed the hash-chain fog/edge (HCFE) protocol, which provides a novel mutual authentication scheme for effective session key agreement (using ZKP properties) with secure protocol communications. The experiment outcomes proved that the hash-chain fog/edge is more efficient at interconnecting various devices and competed favorably in the benchmark comparison.

Application of Machine Learning Algorithms in the Mitigation Phase of Disaster Management - A review

The Mitigation phase in disaster management (DM) is a widely researched subject, and rightly so due to its invaluable role in dampening the consequences of disasters on life and property. A successful mitigation phase serves to be a solid foundation for the smooth execution of the subsequent phases in DM. This paper looks at some of the recent studies and developments pertinent to the mitigation phase in DM, in an attempt to deduce the prevalent Machine Learning (ML) Techniques that are employed across various disaster scenarios. The paper also looks into some of the key factors that have to be considered to ensure a sustainable plan for mitigation.

Optimization of the sintering temperature, cooling time and grain size parameters to reduce residual stresses of copper-aluminum functionally graded material using response surface methodology

One of the urgent needs for the medical, aerospace and military industries is to combine materials with heat-resistant as well as flexible structures. To create such a property, a ceramic must be placed next to metal. FGM materials have such a property in terms of thickness. Functionally graded materials (FGM) are examples of materials with different properties in the thickness direction. In the functionally graded materials, different properties can be created, by changing the percent weight of materials in each layer. It is very important to study the number of residual stresses in these materials due to the fact that several materials with different properties are combined with each other. The purpose of this study is to investigate the effect of production parameters on the number of residual stresses in the aluminum-copper FGM part and also to optimize the production process of these materials. The results indicate that the number of residual stresses decreases with increasing the sintering temperature, cooling time of the sample as well as uniformity along the thickness. In the experiments, the maximum residual stress was 171 MPa, which was obtained for a grain size of 100 microns, sintering temperature of 600°C and cooling time of 24 h and the minimum value of pressure residual stress was 120 MPa, which was obtained for grain size of 20 microns, sintering temperature of 900°C and cooling time of 48 h. Also, finite element modeling of the process was performed and shown a good agreement with experimental results.

Sailing and insight reproduction of Geo-Socio-Cultural unity of Nusantara/Indonesia Maritime: A study focus of Maritime Anthropology

This paper aims to explain how Indonesia was conceptualized as the Indonesian Maritime Continent. From a geo-social perspective, maritime culture can be viewed in, three major dimensions. First, Indonesia is one of the largest archipelagic countries in the world with all the geographical potential, invaluable marine, and maritime resources; second, the potential for socio-cultural, socio-demographic, socio-economic, and long maritime cultural history within the framework of the unity of the Republic of Indonesia; and third, the existence of academic core and the maritime vision of Unhas, the idea of the Indonesian Maritime Continental Development which was launched by the government in 1995/1996, and the vision of maritime national development by President Joko Widodo marked the role of academics and governments in the dynamic process of development to the phase of maritime civilization in the future. In the context of developing maritime ethnographic studies and anthropological contributions to the development of maritime civilization in the future, ideas and academic commitment are needed to make the Indonesian Archipelagic State a large and unique area of maritime socio-cultural research development in the world and Southeast Asia in particular. Thus, interdisciplinary, transdisciplinary, comparative, and multidisciplinary research is needed to carry out broadly and intensively. For this reason, through my inauguration speech for Professor of Anthropology in Hasanuddin University, I introduced a focus of maritime anthropology studies on sailing experiences and the reproduction of Nusantara/Indonesian maritime geo-socio-cultural insights. Through the application of the concept of experience and reproduction of maritime geo-socio-cultural insights which were developed from the concept of maritime ethos disposition theory of reproduction from A.H.J. Prins as a mode of description and analysis, I found the categories of maritime cultural insights and attitudes of Indonesian sailors. They understand most of the territorial waters of the Nusantara (archipelago) and the resources within as common property, a space for interaction between groups of sailors who are diverse in their maritime ethnicity and culture, which in turn strengthens awareness and recognition of the unity of the homeland, culture, and nation that is Bhinneka Tunggal Ika (unity in diversity).

Transmission of SARS-CoV-2 Indoor and Outdoor Environments

Since the outbreak in late December 2019, the coronavirus disease 2019 (COVID-19) pandemic has spread across the globe, causing great damage to human life and property. A lot of researchers around the world have devoted themselves to the study of its origin, pathogenic mechanism, and transmission route, and this article gives a summary. First, both humans and animals can act as the host of coronavirus. In indoor environments, the virus may exist in aerosols, droplets, saliva, etc., from the nose and mouth connected to the respiratory system, as well as feces, urine, etc., from the digestive and urinary systems. In addition, other substances, such as breast milk, eye feces, and blood, released from the host can carry viruses. The virus transmitted indoors is affected by indoor machinery, natural forces, and human activities, and spreads in different distances. Second, the virus spreads outdoors through three kinds of media: solid, liquid, and gas, and is affected by their survival time, the temperature, and humidity in the environment.

Arcadia, The Museum Of Nature

<p>The loss of indigenous ancient forests has had a great impact to New Zealand habitats. Native birds, insects, fungi, plants and animals have been diminishing in diversity since human occupation. This is to a degree the result of intensive resource consumption and demand. Forestry, agriculture, mineral and gas resources were seen as more valuable than the ecosystems that existed before them. Our landscapes themselves became secondary. The particular infrastructure of open cast mining was chosen for this research. Mining represents a way to design active reclamation, while the mine site is still operating. Because of this, time becomes an integral component to the design process. The site is situated at Macraes flat, Otago. Ten kilometres of open cast mine, in operation since 1990. Open cast mining has produced great income. However, The cost of mining extends beyond an eyesore, it diminishes the quality of the land for any future use. Arcadia, the Museum of Nature is a vision of a place for preservation and for pride in ancestral property. A true “Arcadia” — a land of natural wonder. This is a museum of New Zealand’s key indigenous species. One designed through myth woven narratives, inspired by existing authors and generated through narrative experiments. To inspire, educate and showcase our unique ecologies, and endangered environments for future generations. Arcadia becomes a place to witness the succession of the natural world. A continuous time scale allows for a regenerative solution over years to centuries. Thereby showing the ability and resilience of nature in taking back from man’s intrusive tendencies. Rectifying the grotesque interruption of one of nature’s greatest tools, that of time. All the while harbouring our rare and unique wildlife. The museum of nature replaces the current system of remediation, and provides a more provocative solution to the end of modern day infrastructure.</p>

The Potential and Pitfalls of Collector Collaboration in Southeast Arizona

ABSTRACT In locales where much of the archaeological record has been destroyed or heavily impacted by pothunting and development, engaging with collector informants—including those who legally excavated sites on private property in the 1980s—can help fill crucial information gaps. However, such collaboration can pose ethical, and potentially legal, challenges. In this article, I outline research goals and results from a survey project in southeast Arizona's York-Duncan Valley, discuss the legal and ethical implications involved in working with former pothunters, and offer a critical evaluation of project practice. Finally, I offer a set of recommendations for those considering similar collaborations. I argue that the rejection of individuals who are knowledgeable about damaged or destroyed archaeological sites effectively silences the sites forever. Data acquired from former pothunters led to the identification and recording of 25 of 87 archaeological sites in the York-Duncan Valley. These individuals also served as interlocutors with others in the local community, helping us foster the trusted relationships necessary to promote site preservation on private property. A long-term engagement strategy that incorporates an assessment determining whether collector informants are responsible or responsive and that nurtures community involvement in preserving local archaeology offers a more productive course of action.
