The system integrates Machine-to-Machine (M2M) communication and Internet of Things (IoT) protocols within a decentralized framework to facilitate secure, real-time interactions between devices and users. It features a multi-layered design comprising communication, security, and application layers, ensuring dependable functionality and modularity. The Supersingular Isogeny Diffie-Hellman (SIDH) protocol provides security for device-to-device and user interactions with post-quantum cryptographic protection. System behavior is simulated using Cisco Packet Tracer, and additional protocols, such as WebSocket (via websocat), UDP (User Datagram Protocol), and TCP (Transmission Control Protocol), are tested to enhance interactivity and communication efficiency. The architecture assigns distinct roles to users and administrators, establishing clear access and control privileges. Additionally, the framework explores the coordinated optimization of sustainable energy use among neighbouring smart homes. Key performance indicators include system security, latency, communication throughput, and energy efficiency. This proposed model seeks to offer a secure and scalable solution for the future of smart home systems.

energy management in smart home environments. The system integrates Machine-to-Machine (M2M) communication and Internet of Things (IoT) protocols within a decentralized framework to facilitate secure, real-time interactions between devices and users. It features a multi-layered design comprising communication, security, and application layers, ensuring dependable functionality and modularity. The Supersingular Isogeny Diffie-Hellman (SIDH) protocol provides security for device-to-device and user interactions with post-quantum cryptographic protection. System behavior is simulated using Cisco Packet Tracer, and additional protocols, such as WebSocket (via websocat), UDP (User Datagram Protocol), and TCP (Transmission Control Protocol), are tested to enhance interactivity and communication efficiency. The architecture assigns distinct roles to users and administrators, establishing clear access and control privileges. Additionally, the framework explores the coordinated optimization of sustainable energy use among neighbouring smart homes. Key performance indicators include system security, latency, communication throughput, and energy efficiency. This proposed model seeks to offer a secure and scalable solution for the future of smart home systems.\u003c/p\u003e","manuscriptTitle":"Secure and Sustainable Smart Home Networks with Blockchain-Based IoT Framework for Privacy and Energy Efficiency","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-06 07:13:07","doi":"10.21203/rs.3.rs-7454958/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-10-27T10:15:11+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-20T20:44:05+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-18T16:33:57+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-07T04:31:52+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"276582177467517591475121806939203000991","date":"2025-09-29T06:09:17+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"28747210113872008566528947568767294659","date":"2025-09-25T14:17:59+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"318656249596596589600133369840712398454","date":"2025-09-24T15:22:36+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"316858646976679449973843822202040508802","date":"2025-09-24T08:21:55+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-09-24T05:19:28+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"283600535113880377037207672384737104325","date":"2025-09-24T05:09:28+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"332251058193828266992302778350379546705","date":"2025-09-23T19:35:40+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"229432271927036948250218748348027968027","date":"2025-09-23T15:51:42+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-09-23T14:10:13+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"95753738412384366642055061042542365458","date":"2025-09-23T14:02:51+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-09-23T13:49:22+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2025-09-18T06:55:22+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-09-17T12:27:58+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-09-11T18:13:04+00:00","index":"","fulltext":""},{"type":"submitted","content":"Discover Internet of Things","date":"2025-09-11T18:08:58+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"discover-internet-of-things","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"diot","sideBox":"Learn more about [Discover Internet of Things](https://www.springer.com/journal/43926)","snPcode":"","submissionUrl":"","title":"Discover Internet of Things","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"stoa","reportingPortfolio":"Discover Series","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"de2e7410-218e-4d97-99e7-e4f453ce1c19","owner":[],"postedDate":"October 6th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2026-05-04T16:04:22+00:00","versionOfRecord":{"articleIdentity":"rs-7454958","link":"https://doi.org/10.1007/s43926-026-00297-8","journal":{"identity":"discover-internet-of-things","isVorOnly":false,"title":"Discover Internet of Things"},"publishedOn":"2026-04-30 15:57:27","publishedOnDateReadable":"April 30th, 2026"},"versionCreatedAt":"2025-10-06 07:13:07","video":"","vorDoi":"10.1007/s43926-026-00297-8","vorDoiUrl":"https://doi.org/10.1007/s43926-026-00297-8","workflowStages":[]},"version":"v1","identity":"rs-7454958","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7454958","identity":"rs-7454958","version":["v1"]},"buildId":"XKTyCvWXoU3ODBz1xrDgd","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
