Fast and Efficient Security Scheme for Blockchain-Based IoT Networks

Internet of Things (IoT) has become widely used nowadays and tremendous increase in the number users raises its security requirements as well. The constraints on resources such low computational capabilities power demand lightweight cryptosystems. Conventional algorithms are not applicable IoT network communications because mentioned above. In this work, a novel efficient scheme for providing applications is introduced. proposes how can be enhanced distributed application by multilevel protection dynamic key generation data uploading transfer phases. Existing works rely single communication between sensing device attached gateway node. proposed scheme, session updated after each done applying principles cellular automata. system provides using incomparable benefits blockchain, random based same was implemented tested with known protocol verification tool called Automated Validation Security Protocols Applications (AVISPA). Results show that secure against various attacks. been compared related schemes result analysis shows new fast also.
