Lightweight Blockchain-Based Scheme to Secure Wireless M2M Area Networks

Security is a challenging issue for M2M/IoT applications due to the deployment, decentralization and heterogeneity of M2M IoT devices. Typical security solutions may not be suitable systems regarding difficulties encountered their implementation on resource-constrained In this paper, we discuss architectures deployed communications challenges, as well vulnerabilities counter possible attacks. We present lightweight design based private blockchain secure wireless at device domain level. Blockchain integration provides storage data while preserving integrity traceability availability. Besides, evaluation experimentations under NS3 simulator proposed scheme show that authentication mechanism lightweight, presents better performances comparatively other protocols in terms key parameters communication computational overheads, average delay energy consumption.
