A Novel Blockchain Secure to Routing Protocol in WSN

A blockchain is a database that contains the history of all exchanges made between its users since its creation. A blockchain is a distributed and secure ledger of all transactions made since the start of the distributed system. It is a technology for storing and transmitting information, transparent, secure, and operating without a central control body. Our paper studies a new device authentication for mobile sensor node to prove its authenticity to unknown network manager. To solve the authentication of sensor among multiple networks, our proposal a blockchain scheme where the transaction specifies the authentication of given cluster head CH. As we claim, a blockchain guarantees an integrity and availability of message under assumption that every node has some public and private key pairs. However, it does not provide any authentication mechanism for symmetric key. Hence, the proposed scheme is secure as we claim. More concretely, in the protocol proposed Blockchain Security IoT (BSI) is to provide authentication between the mobile base station (BS), the cluster head and the member nodes for wireless sensor networks (WSN). Our protocol BSI protocol makes it possible to put the necessary keys of the networks at the level of each sensor for the different scenarios carried out, BS mobile node and migration node. We evaluate the performance of our protocol with simulations using MATLAB. The results confirm that the BSI protocol is robust and efficient, provides lower power consumption and fast computing time.
