Blockchain Secured Distributed Computing for Low Resource Edge Devices in IoT Systems

Edge Devices in IoT systems have limited computing power, run on primitive operating systems, and mostly communicate through typical wireless IoT network protocols. IoT systems may require high computation power, large bandwidth connection, and rely mostly on the third party for centralized database and computation which causes latency and exposes the system to security loopholes. With the increasing adoption of IoT systems, there is a need to localize computing and reduce the need for large bandwidth connections. This paper proposes a model for distributed computing in low-resource edge devices connected in an IoT system secured with a decentralized private blockchain. The model uses a unique identity key for node identification, a public key for blockchain, and proof-of-work. The main objective of the proposed model is to create an IoT system that does not require third-party computation, database, and securing IoT system from illegal access control, as well as allowing for secure communication between local IoT devices.
