A Blockchain Based Decentralized Platform for Ubiquitous Learning Environment

摘要

Internet of Things (IoT) and Blockchain (BC) is an innovative paradigm that is gaining ground in smart environments. In intelligent classrooms, IoT makes our exchange easier with the prominent advent of smart devices, connected objects and sensors. However, the important research direction in this kind of IoT-Based Ubiquitous Learning Environment (ULE) is security and privacy that remaining essential challenges. Previously, we exposed the initial architecture of ULE based on BC technology and the educational services that can be delivered via this platform. In this paper, we investigate deeper and we highlight the main component of our ULE known as integrated IoT-ubiquitous platform using BC. The collection of data exchanged across devices is determined by the miner that preserves security using transactions that trace communications. Finally, in this study we demonstrate our preliminary experimental results that show the effectiveness of the proposed decentralized platform which is more secure by analyzing confidentiality, integrity, and availability.
