Since Facebook officially changed its name to Meta in Oct. 2021, the metaverse has become a new norm of social networks and three-dimensional (3D) virtual worlds. The aims bring 3D immersive personalized experiences users by leveraging many pertinent technologies. Despite great attention benefits, natural question is how secure users' digital content data. In this regard, blockchain promising solution owing distinct features decentralization, immutability, transparency. To better understand role metaverse, we aim provide an extensive survey on applications for metaverse. We first present preliminary highlight motivations behind use Next, extensively discuss blockchain-based methods from technical perspectives, such as data acquisition, storage, sharing, interoperability, privacy preservation. For each perspective, challenges then can help. Moreover, investigate impact key-enabling technologies including Internet-of-Things, twins, multi-sensory applications, artificial intelligence, big also some major projects showcase services. Finally, directions drive further research innovations developments toward future.

Blockchain-Based Federated Learning for Securing Internet of Things: A Comprehensive Survey

ACM Computing Surveys, Год журнала: 2022, Номер 55(9), С. 1 - 43

Опубликована: Сен. 6, 2022

The Internet of Things (IoT) ecosystem connects physical devices to the internet, offering significant advantages in agility, responsiveness, and potential environmental benefits. number variety IoT are sharply increasing, as they do, generate data sources. Deep learning (DL) algorithms increasingly integrated into applications learn infer patterns make intelligent decisions. However, current paradigms rely on centralized storage computing operate DL algorithms. This key central component can potentially cause issues scalability, security threats, privacy breaches. Federated (FL) has emerged a new paradigm for preserve privacy. Although FL helps reduce leakage by avoiding transferring client data, it still many challenges related models’ vulnerabilities attacks. With emergence blockchain smart contracts, utilization these technologies safeguard across ecosystems. study aims review blockchain-based methods securing systems holistically. It presents state research blockchain, how be applied approaches, issues, responses outline need use emerging approaches toward also focuses analytics from perspective open questions. provides thorough literature applications. Finally, risks associated with integrating discussed considered future works.

Anomaly Detection in Blockchain Networks: A Comprehensive Survey

IEEE Communications Surveys & Tutorials, Год журнала: 2022, Номер 25(1), С. 289 - 318

Опубликована: Сен. 12, 2022

Over the past decade, blockchain technology has attracted a huge attention from both industry and academia because it can be integrated with large number of everyday applications modern information communication technologies (ICT). Peer-to-peer (P2P) architecture enhances these by providing strong security trust-oriented guarantees, such as immutability, verifiability, decentralization. Despite incredible features that brings to ICT applications, recent research indicated guarantees are not sufficient enough networks may still prone various security, privacy, reliability issues. In order overcome issues, is important identify anomalous behaviour within actionable time frame. this article, we provide an in-depth survey regarding integration anomaly detection models in technology. For this, first discuss how aid ensuring based applications. Then, demonstrate certain fundamental evaluation metrics key requirements play critical role while developing for blockchain. Afterwards, present thorough perspective each layer Finally, conclude article highlighting challenges alongside discussing they serve future directions new researchers field.

With the rapid enhancement in design and development of Internet Things creates a new research interest adaptation industrial domains. It is due to impact distributed emerging technology topology security-related resource constraints 5.0. This conducts paradigm along with critical challenges existing information preservation, node transactions communication, transmission, trust privacy, security protection related problems. These aspects pose serious limitations issues for industry provide data integrity, exchange reliability, provenance, trustworthiness overall activities service delivery prospects. In addition, intersection blockchain IoT has gained more consideration interest. However, there an limitation between inadequate performance connected nodes, high requirement permissioned private ledger not yet been tackled complete solution. Due introductions NuCypher Re-Encryption infrastructure, hashing tree allocation, deployment proof-of-work required computational power as well. paper divided into three different folds; first, we studied various literature blockchain-enabling its implementation challenging Secondly, proposed hyperledger sawtooth-enabled framework. framework provides secure trusted execution environment, which mechanisms protocols are designed acknowledgment, including immutable storage security, peer-to-peer network on-chain off-chain communication activities. Thirdly, pseudo-chain codes consensus smooth streamline broadcast content.

Опубликована: Ноя. 13, 2022

Some of the significant new technologies researched in recent studies include BlockChain (BC), Software Defined Networking (SDN), and Smart Industrial Internet Things (IIoT). All three provide data integrity, confidentiality, integrity their respective use cases (especially industrial fields). Additionally, cloud computing has been for several years now. Confidential information is exchanged with infrastructure to clients access distant resources, such as storage activities IIoT. There are also security risks, concerns, difficulties associated computing. To address these challenges, we propose merging BC SDN into a platform This paper introduces "DistB-SDCloud", an architecture enhanced smart IIoT applications. The proposed uses distributed method security, secrecy, privacy, while remaining flexible scalable. Customers sector benefit from dispersed or decentralized, efficient environment BC. described improve durability, stability, load balancing infrastructure. efficacy our BC-based implementation was experimentally tested by using various parameters including throughput, packet analysis, response time, bandwidth, latency well monitoring attacks on system itself.
