BLOCKCHAIN BASED WI-FI ONBOARDING SIMPLIFICATION, IDENTITY MANAGEMENT AND DEVICE PROFILING FOR IOT DEVICES IN ENTERPRISE NETWORKS

A consortium blockchain fabric is provided as a Digital Network Architecture Center (DNAC) Application (APP) stack running in a Cloud Neutral Facility. This consortium blockchain fabric achieves two important functions: Verification of Internet of Things (IoT) Vendor Installed Identity and IoT Device Network Usage Profile. Verification of IoT Vendor Installed Identity. IoT device vendors will be part of the IoT consortium that maintains the blockchain fabric. The manufacturer installed identity credentials of the devices are registered on the blockchain. This allows the enterprises to verify the manufacturer installed identity of the device at the time of onboarding. IoT Device Network Usage Profile. These are the traffic flow characteristics of the IoT application. The IoT service provider is responsible for registering the network usage profile on the blockchain fabric. IoT service providers will be consortium members. In many cases, the IoT vendor and the IoT service provider will be the same entity

A Framework for Handling Internet of Things Data with Confidentiality and Blockchain Support

The Internet of Things (IoT) has emerged as a disruptive technology in recent time. Due to a sharp rise in the deployment of IoT devices across the globe, the total amount of generated data reaching record highs every day. There is no denying that IoT devices with the data that they produce enhancing our day to day lives by bringing in innovative solutions. However, there is a darker side of this technology as it enables device manufacturers and service providers to retain this data that they can later use for several purposes, including targeted marketing. Unfortunately, not many people are aware of this data misuse by service providers. To address this issue, we propose a framework for the confidential handling of IoT data with Blockchain-based verification. We used a combination of Solid and Blockchain to accomplish this goal. Our experimental results show that the proposed approach is promising and has the potential to bring a considerable change in the IoT industry

When Mobile Blockchain Meets Edge Computing

Blockchain, as the backbone technology of the current popular Bitcoin digital currency, has become a promising decentralized data management framework. Although blockchain has been widely adopted in many applications, e.g., finance, healthcare, and logistics, its application in mobile services is still limited. This is due to the fact that blockchain users need to solve preset proof-of-work puzzles to add new data, i.e., a block, to the blockchain. Solving the proof-of-work, however, consumes substantial resources in terms of CPU time and energy, which is not suitable for resource-limited mobile devices. To facilitate blockchain applications in future mobile Internet of Things systems, multiple access mobile edge computing appears to be an auspicious solution to solve the proof-of-work puzzles for mobile users. We first introduce a novel concept of edge computing for mobile blockchain. Then, we introduce an economic approach for edge computing resource management. Moreover, a prototype of mobile edge computing enabled blockchain systems is presented with experimental results to justify the proposed concept.Comment: Accepted by IEEE Communications Magazin
