A blockchain-based trust management system for 5G network slicing enabled C-RAN

The mobility nature of the wireless networks and the time-sensitive tasks make it necessary for the system to transfer the messages with a minimum delay. Cloud Radio Access Network (C-RAN) reduces the latency problem. However, due to the trustlessness of 5G networks resulting from the heterogeneity nature of devices. In this article, for the edge devices, there is a need to maintain a trust level in the C-RAN node by checking the rates of devices that are allowed to share data among other devices. The SDN controller is built into a macro-cell that plays the role of a cluster head. The blockchain-based automatically authenticates the edge devices by assigning a unique identification that is shared by the cluster head with all C-RAN nodes connected to it. Simulation results demonstrate that, compared with the benchmark, the proposed approach significantly improves the processing time of blocks, the detection accuracy of malicious nodes, and transaction transmission delay

Security, Trust and Privacy in Cyber (STPCyber): Future trends and challenges

© 2020 Today's world experiences massively interconnected devices to share information across variety of platforms between traditional computers (machines), Smart IoT devices used across smart homes, smart interconnected vehicles etc. and of course the social networks apps such as Facebook, Linkdn, twitter etc. We experience the growth has been skyrocketing and the trend will continue exponentially to the future. At one end, we find life becomes easier with such developments and at the other end; we experience more and more cyber threats on our privacy, security and trustworthiness with organizations holding our data. In this special issue, we summarize contributions by authors in advanced topics related to security, trust and privacy based on a range of applications and present a selection of the most recent research efforts in these areas
