Abstract: 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.

Abstract: This disclosure relates to field of cryptography and digital signatures. The constant theft of cryptocurrencies is due to compromise of the secret signing key inherently stored in a single location. Also, one of challenges in the existing ECDSA signature is single point failure, wherein the signing key (private key) is prone to theft. The disclosed technique overcomes the challenging in the existing techniques by party distributed signature that ensures the safety of the private key. The disclosed techniques slits the key in two parts and saves at two different locations/machines. Further based on a ECDSA based technique, the digital signature is obtained securely using several steps that includes generation of first two parts of digital signature at one party, generation of the second two parts of digital signature at second party, finally decrypting a complete digital signature at the first party.

Abstract: This disclosure relates generally to method and system for securing peer nodes in a blockchain network. The proposed disclosure is a robust model providing secure, scalable and efficient sharding committee reconfiguration technique where blockchain peer nodes organize themselves into each sharding committee among a plurality of sharding committees. The disclosure includes, generating a random number directory by each peer node communicating random numbers to the reference committee through leader node in the blockchain network. The reference committee initiates to reconfigure members of each sharding committee at predefined intervals. Further, a first message packet from each peer node is received by the reference committee based on which a second message packet is generated enabling each peer node of the block chain network to join one of the sharding committee.
