This disclosure relates generally to method and system for secure IoT device onboarding using a blockchain network. Internet of Things (IoT) device onboarding is a challenging problem as it needs to be securely connected to its actual final owner, with minimal manual intervention. Onboarding provides provisioning the IoT devices with credentials for accessing a network resource and assigning appropriate permissions. The present disclosure establishes a mutual authentication between at least one IoT device from the one or more IoT devices and a TIMS. Further, based on the verified authentication the TIMS enables the device to identify its current owner using a blockchain network. Further, the IoT device authenticating parameter is computed for authentication of the TIMS with at least one IoT device from the one or more IoT devices.

Method and system for secure IoT device onboarding using a blockchain network

This disclosure relates generally to decentralized storage and more particularly to method and system for blockchain based decentralized storage with dynamic data operations. Conventional decentralized storage are limited in capacity thereof to enable dynamic data operations on the sectors stored at them. In an embodiment, the disclosed method and system enabled dynamic data operations such as modification, insertion, and deletion on the stored sectors by leveraging blockchain to achieve publicly verifiable fully stateless Provable Data Possession. Moreover, the disclosed system enables data integrity in decentralized storage with dynamic operations using scheme based on Merkle hash tree and blockchain to provide a transparent verification framework with high detection probability of malicious hosts.
