Abstract
The inherent challenges associated with the Internet of Things (IoT), such as vulnerability to cyber threats and privacy issues, need the development of novel solutions to ensure secure and efficient handling of data. Fog computing resolves these concerns by facilitating data processing in proximity to edge devices, minimising latency, and improving real-time decision-making. Blockchain boosts security in fog-based systems by providing a tamper-proof and transparent ledger. However, exclusively prioritising privacy in fog-based blockchains may impede the practical execution. This article presents the FogBlock Connect paradigm, which combines Fog computing and Blockchain through the implementation of a tailored Proxy Re-encryption (PRE) algorithm inspired by BBS98. This strategy guarantees enhanced data confidentiality while simultaneously upholding operational effectiveness in fog-based blockchains for Internet of Things applications. The efficiency and effectiveness of the suggested PRE algorithm over typical encryption methods are confirmed by comprehensive simulations utilising the Fobsim simulator. The FogBlock Connect paradigm entails the transmission of updates from nearby IoT devices to Fog servers for the purpose of creating and securely storing global updates, hence improving efficiency and performance. The paradigm ensures robust privacy measures, mitigates risks of single-point failures, and facilitates precise access control, establishing a basis for secure and resilient IoT applications. The CCA resistant formal security proof provides further validation for the strength and effectiveness of the suggested approach.
期刊介绍：
The aim of the Peer-to-Peer Networking and Applications journal is to disseminate state-of-the-art research and development results in this rapidly growing research area, to facilitate the deployment of P2P networking and applications, and to bring together the academic and industry communities, with the goal of fostering interaction to promote further research interests and activities, thus enabling new P2P applications and services. The journal not only addresses research topics related to networking and communications theory, but also considers the standardization, economic, and engineering aspects of P2P technologies, and their impacts on software engineering, computer engineering, networked communication, and security.
The journal serves as a forum for tackling the technical problems arising from both file sharing and media streaming applications. It also includes state-of-the-art technologies in the P2P security domain.
Peer-to-Peer Networking and Applications publishes regular papers, tutorials and review papers, case studies, and correspondence from the research, development, and standardization communities. Papers addressing system, application, and service issues are encouraged.
