First, the honey encryption (HE) technology and advanced encryption standard (AES) are combined to propose a new encryption algorithm HE-AES, which is used to encrypt the preprocessed data. Second, the Kademlia algorithm is embedded in the edge server to realize the distributed storage and automatic recovery of microgrid data. Finally, the traditional proof of authority (PoA) consensus mechanism is improved partially, and the improved PoA is used to make each node reach consensus and pack blocks on the chain. The scheme can not only realize the data disaster backup automatically but also has high efficiency of data processing, which can provide a new idea for improving the current data disaster backup schemes.<\/jats:p>","DOI":"10.1155\/2021\/9121571","type":"journal-article","created":{"date-parts":[[2021,8,3]],"date-time":"2021-08-03T23:50:14Z","timestamp":1628034614000},"page":"1-19","source":"Crossref","is-referenced-by-count":4,"title":["A Blockchain-Based Microgrid Data Disaster Backup Scheme in Edge Computing"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5353-6875","authenticated-orcid":true,"given":"Lihua","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Software, East China Jiaotong University, Nanchang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7209-8452","authenticated-orcid":true,"given":"Yu","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Electrical and Automation Engineering, East China Jiaotong University, Nanchang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0092-5380","authenticated-orcid":true,"given":"Ganzhe","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Electrical and Automation Engineering, East China Jiaotong University, Nanchang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2070-7703","authenticated-orcid":true,"given":"Yang","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Software, East China Jiaotong University, Nanchang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8867-7216","authenticated-orcid":true,"given":"Chen","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Electrical and Automation Engineering, East China Jiaotong University, Nanchang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/tsg.2017.2777975"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2019.04.011"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2020.07.017"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/comst.2019.2894727"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.cose.2020.102010"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/s10586-020-03058-6"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s12652-021-03021-2"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/6694729"},{"first-page":"605","article-title":"Automatic discovery mechanism of blockchain nodes based on the Kademlia algorithm","author":"L.
