Completely FROST-ed: IoT issued FROST signature for Hyperledger Fabric blockchain

Threshold signatures play a crucial role in the security of blockchain applications. An efficient threshold signature can be applied to enhance the security of wallets and transactions by enforcing multi-device-based authentication, as this requires adversaries to compromise more devices to recover the key. Additionally, threshold signatures can...

Blockchain-empowered federated learning based solutions for Internet of Things security, privacy, and performance

The Internet of Things (IoT) is a rapidly growing technology that connects millions of devices together. However, as more devices connect, the importance of ensuring security, privacy, and performance becomes paramount. Training performance is affected without proper protocols in place, and devices can get compromised. This research focuses on...

A study on the implementation of digital technologies for improving steel reuse

The present research tries to promote circularity in steel structures by attempting to further incorporate technologies like BIM, the Internet of Things (IoT), and Blockchain in the AEC industry. BIM is already applied in construction projects but not yet focused on aspects that will enhance the reusability of steel structures. IoT and...

On Designing Smart Agents for Service Provisioning in Blockchain-Powered Systems

Service provisioning systems assign users to service providers according to allocation criteria that strike an optimal trade-off between users' Quality of Experience (QoE) and the operation cost endured by providers. These systems have been leveraging Smart Contracts (SCs) to add trust and transparency to their criteria. However, deploying...

Blockchain-based DNS and PKI to solve issues of trust, security and censorship in the context of the IoT

The domain name system (DNS) and public key infrastructure (PKI) provide the core services for the Internet. The use of these systems requires trust in institutions to provide proper services, which they can fail to provide. Centralized management allows these institutions to perform censorship. Additionally, these legacy systems have seen...

Blockchain-based frameworks for mitigating DDoS and Sybil attacks in the IoT

With the growing scale of the IoT, many industries enjoy the benefit of automation. The IoT consists of an interconnected network of devices that sense their surroundings and share data among other IoT devices. However, this data can be sensitive and private in nature, making security within the ever-growing IoT network a high priority. Because...

Improving data integrity and fault tolerance in IoT networks with Blockchain: on the search for suitable consensus mechanisms

IoT devices have grown rapidly over the past few years. IoT devices are mostly connected to a central server that stores the data and handles end-to-end communication. Due to the increase of IoT devices, the latency with the server increases. Furthermore, when using a central server the data is at risk of being deleted or tampered with. To...

A new blockchain system design to improve the supply chain of engineering, procurement and construction (EPC) companies – a case study in the oil and gas sector

Purpose: This paper aims to propose a new blockchain system design to improve engineering, procurement and construction (EPC) companies’ supply chain for constructing oil and gas infrastructure, by mitigating cost and time inefficiencies. Design/methodology/approach: A case study analyses the supply chain of a sample EPC company. First, a...

Internet-of-Forensic (IoF): A blockchain based digital forensics framework for IoT applications

Digital forensic in Internet-of-Thing (IoT) paradigm is critical due to its heterogeneity and lack of transparency of evidence processing. Moreover, cross-border legalization makes a hindrance in such process pertaining to the cloud forensic issues. This urges a forensic framework for IoT which provides distributed computing, decentralization...
