Web3.0 Security: Privacy Enhancing and Anonym Auditing in Blockchain-based Structures

The advent of Web 3.0, underpinned by blockchain technologies, promises to transform the internet's landscape by empowering individuals with decentralized control over their data. However, this evolution brings unique security challenges that need to be addressed. This paper explores these complexities, focusing on enhancing privacy and anonymous auditing within blockchain structures. We present the architecture of Web 3.0 based on the blockchain, providing a clear perspective on its workflow and security mechanisms. A security protocol for Web 3.0 systems, employing privacy-preserving techniques and anonymous auditing during runtime, is proposed. Key components of our solution include the integration of privacy-enhancing techniques and the utilization of Tor for anonymous auditing. We discuss related work and propose a framework that meets these new security requirements. Lastly, we offer an evaluation and comparison of our model to existing methods. This research contributes towards the foundational understanding of Web 3.0's secure structure and offers a pathway towards secure and privacy-preserving digital interactions in this novel internet landscape

The Intersection of Cloud Computing and Smart Cities: An Exploratory Review of Applications and Challenges in Deployment

This research addressed the intersection of cloud computing and smart cities. Cloud computing and smart cities are two areas that are seeing fast expansion and have the potential to transform the manner in which we work and live. Cloud computing facilitates the supply of on-demand computing resources, including storage, networking, and software, via the internet; and smart cities use technology to improve the quality of life for inhabitants and the efficiency of municipal services. According to the findings of the research, cloud computing has the potential to be used in diverse applications within smart cities. Some examples of these applications include smart transportation, smart lighting, smart buildings, smart waste management, smart healthcare, smart parking, and smart citizen services. This study also drew attention to a number of obstacles that need to be overcome before cloud computing may be properly implemented. Concerns around data security and privacy, network and connection, interoperability, dependency on internet access, cost and scalability, and the need for successful cooperation between municipal authorities, technology suppliers, and residents are examples of these problems. The findings of the research indicate that the potential for cloud computing to significantly improve the capabilities of smart cities should not be underestimated, despite the fact that there are considerable obstacles to be addressed. It will be vital for municipal authorities, technology providers, and residents to collaborate to overcome the problems and establish successful methods for adopting cloud computing in smart cities if this promise is going to be realized

Access Management in Lightweight IoT: A Comprehensive review of ACE-OAuth framework

With the expansion of Internet of Things (IoT), the need for secure and scalable authentication and authorization mechanism for resource-constrained devices is becoming increasingly important. This thesis reviews the authentication and authorization mechanisms in resource-constrained Internet of Things (IoT) environments. The thesis focuses on the ACE-OAuth framework, which is a lightweight and scalable solution for access management in IoT. Traditional access management protocols are not well-suited for the resource-constrained environment of IoT devices. This makes the lightweight devices vulnerable to cyber-attacks and unauthorized access. This thesis explores the security mechanisms and standards, the protocol flow and comparison of ACE-OAuth profiles. It underlines their potential risks involved with the implementation. The thesis delves into the existing and emerging trends technologies of resource-constrained IoT and identifies limitations and potential threats in existing authentication and authorization methods. Furthermore, comparative analysis of ACE profiles demonstrated that the DTLS profile enables constrained servers to effectively handle client authentication and authorization. The OSCORE provides enhanced security and non-repudiation due to the Proof-of-Possession (PoP) mechanism, requiring client to prove the possession of cryptographic key to generate the access token. The key findings in this thesis, including security implications, strengths, and weaknesses for ACE OAuth profiles are covered in-depth. It shows that the ACE-OAuth framework’s strengths lie in its customization capabilities and scalability. This thesis demonstrates the practical applications and benefits of ACE-OAuth framework in diverse IoT deployments through implementation in smart home and factory use cases. Through these discussions, the research advances the application of authentication and authorization mechanisms and provides practical insights into overcoming the challenges in constrained IoT settings

Security Limitations with Cloud Computing: Well-defined Security Measures Using Cloud Computing

Due to the ever-growing threat of security breaches that information technology (IT) organizations continually face, protecting customer information stored in the cloud is critical to ensure data integrity. Research shows that new categories of data breaches frequently emerge; thus, security strategies that build trust in consumers and improve system performance are crucial. The purpose of this qualitative multiple case study was to explore and analyze the strategies used by database administrators (DBAs) to secure data in a private infrastructure as a service (IaaS) cloud environment. The participants comprised of six DBAs from two IT companies in Baltimore, Maryland, with experience and knowledge of security strategies to secure data in private IaaS clouds. The disruptive innovation theory was the foundational framework for this study. Data were collected using semistructured interviews and a review of seven organizational documents. A thematic analysis was used to analyze the data. Two key themes are addressed in this article: importance of well-defined security measures in cloud computing and limitations of existing security controls in cloud computing. The findings of well-defined security strategies may benefit DBAs and IT organizations by providing strategies that may prevent future data breaches. Well-defined security strategies may protect an individual’s data which, in turn, may promote individual well-being and build strong communities.

Factors driving enterprise adoption of blockchain technology

Amidst the rapidly evolving advancement of blockchain technology (BT), enterprises face notable challenges in leveraging its transformative potential, starting with a need to understand the technology and how it can be used for particular applications. Two challenges are that many BT trials have not been successful and large-scale implementations that have led to continued use are scarce. This research provides a comprehensive examination of factors that drive the successful adoption of BT for enterprise use cases. A dual-phased approach was employed. First, I introduce a taxonomy matrix correlating BT design characteristics with use case characteristics, offering a framework for BT design and benefits across different enterprise contexts. Second, I conducted case studies of five successful BT cases in large enterprises that led to the adoption in terms of continued use and contrasted them with one failure case. The data collection and analysis of the case studies encompassed technological, organizational, environmental, and inter-organizational variables that led to BT\u27s continued use. The cross-case analysis revealed that compatibility, relative advantage, and observability are primary technological factors contributing to continued use. Within the organizational dimension, organizational knowledge and internal characteristics emerged as crucial elements, while regulatory compliance came out to be a significant factor. Based on the cross-case analysis, I develop theoretical propositions about the factors that lead to the continued use of BT, which can be further validated and tested in future research
