In this paper, structure of the power IoT is introduced, security risks of the terminal devices in the perception layer of the power IoT are analyzed, and security requirements and authentication technologies of identity authentication of the terminals are studied. Then a lightweight flexible authentication method suitable for terminal devices in the power IoT is proposed to implement direct peer to peer authentication between terminal devices, which is based on the public key encryption technology and the assistance of lightweight certificate server. Relying on this method, the central security risk and performance bottleneck of the certificate server are reduced effectively, the fake attacks against the terminal devices can be prevented, and the illegal use of terminal devices can be found timely.<\/jats:p>","DOI":"10.3233\/jcm-225923","type":"journal-article","created":{"date-parts":[[2022,3,1]],"date-time":"2022-03-01T13:27:02Z","timestamp":1646141222000},"page":"791-800","source":"Crossref","is-referenced-by-count":0,"title":["A method of lightweight flexible terminal device authentication in the power internet of things"],"prefix":"10.66113","volume":"22","author":[{"given":"Xiaoming","family":"Zhou","sequence":"first","affiliation":[{"name":"State Grid Liaoning Electric Power Supply Co., Ltd, Shenyang, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo","family":"Hu","sequence":"additional","affiliation":[{"name":"State Grid Liaoning Electric Power Supply Co., Ltd, Shenyang, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangao","family":"Li","sequence":"additional","affiliation":[{"name":"State Grid Liaoning Electric Power Supply Co., Ltd, Shenyang, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Wang","sequence":"additional","affiliation":[{"name":"State Grid Liaoning Electric Power Supply Co., Ltd, Shenyang, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang","family":"Wang","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Liaoning Electric Power Supply Co., Ltd, Shenyang, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiqi","family":"Gao","sequence":"additional","affiliation":[{"name":"State Grid Dalian Electric Power Supply Co., Ltd, Dalian, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Liu","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Liaoning Electric Power Supply Co., Ltd, Shenyang, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Liu","sequence":"additional","affiliation":[{"name":"Shenyang Institute of Engineering, Shenyang, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenliu","family":"Zhou","sequence":"additional","affiliation":[{"name":"Shenyang Institute of Engineering, Shenyang, Liaoning, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55691","reference":[{"issue":"7","key":"10.3233\/JCM-225923_ref1","doi-asserted-by":"crossref","first-page":"1497","DOI":"10.1016\/j.adhoc.2012.02.016","article-title":"Internet of things","volume":"10","author":"Miorandi","year":"2012","journal-title":"Ad Hoc Networks."},{"issue":"2","key":"10.3233\/JCM-225923_ref2","first-page":"107","article-title":"Key technologies and application prospects of ubiquitous power Internet of things","volume":"40","author":"Yang","year":"2019","journal-title":"Power Generation Technology."},{"issue":"11","key":"10.3233\/JCM-225923_ref4","first-page":"118","article-title":"Network security risk analysis and Countermeasures under the background of ubiquitous power Internet of things","volume":"50","author":"Zou","year":"2020","journal-title":"Power Equipment Management."},{"issue":"5","key":"10.3233\/JCM-225923_ref5","first-page":"1","article-title":"Research on key technologies of ubiquitous power Internet of things","volume":"40","author":"Fu","year":"2019","journal-title":"Electric Power Construction."},{"issue":"05","key":"10.3233\/JCM-225923_ref6","first-page":"146","article-title":"Ubiquitous power Internet of things application in intelligent distribution system","volume":"37","author":"Gu","year":"2020","journal-title":"Telecom Power Technology."},{"issue":"S1","key":"10.3233\/JCM-225923_ref7","first-page":"49","article-title":"Full-scenario situation awareness for power Internet of things solution","author":"Jin","year":"2020","journal-title":"Information Security and Communications Privacy."},{"issue":"09","key":"10.3233\/JCM-225923_ref8","first-page":"246","article-title":"Application of controlled signature algorithm in ubiquitous power Internet of things","volume":"19","author":"Liu","year":"2020","journal-title":"Software Guide."},{"issue":"10","key":"10.3233\/JCM-225923_ref9","first-page":"1","article-title":"Research on identity authentication technology in power Internet of things based on SM9 algorithm","volume":"47","author":"Liao","year":"2020","journal-title":"ShanDong Electric Power."},{"key":"10.3233\/JCM-225923_ref10","doi-asserted-by":"crossref","unstructured":"O\u2019Gorman L.
