Typical security solutions may not be suitable for M2M\/IoT systems regarding the difficulties encountered for their implementation on resource-constrained devices. In this paper, we discuss the architectures deployed for M2M communications and the security challenges, as well as the vulnerabilities and solutions to counter possible attacks. We present a lightweight design based on a private blockchain to secure wireless M2M communications at the device domain level. Blockchain integration provides secure storage of data while preserving integrity traceability and availability. Besides, the evaluation and experimentations under NS3 simulator of the proposed scheme show that the authentication mechanism is lightweight, and presents better performances comparatively to other protocols in terms of key parameters as communication and computational overheads, average delay and energy consumption.<\/jats:p>","DOI":"10.3390\/fi14050158","type":"journal-article","created":{"date-parts":[[2022,5,23]],"date-time":"2022-05-23T22:57:22Z","timestamp":1653346642000},"page":"158","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Lightweight Blockchain-Based Scheme to Secure Wireless M2M Area Networks"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4204-0401","authenticated-orcid":false,"given":"Karam Eddine","family":"Bilami","sequence":"first","affiliation":[{"name":"IRIMAS\/GRTC Institute, University of Haute Alsace, 68008 Colmar, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3346-7216","authenticated-orcid":false,"given":"Pascal","family":"LORENZ","sequence":"additional","affiliation":[{"name":"IRIMAS\/GRTC Institute, University of Haute Alsace, 68008 Colmar, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,23]]},"reference":[{"key":"ref_1","unstructured":"ETSI (2022, April 27).
