With the wide application of unmanned aerial vehicles, position information has also become an important factor in authentication. In this paper, we present a new key exchange protocol, which firstly realizes dual authentication for both password and position, and we propose two applicable scenarios for the PPAKE mechanism: one is unmanned aerial vehicle authentication, and the other one is authentication in the military base. By adding position authentication, the reliability of authentication has improved, and the difficulty of adversarial attacks also increases. Any arbitrary adversary who can listen, tamper, and send messages can only perform an online attack for password guessing at a specified position. Finally, we provide security proofs under the defined model.<\/jats:p>","DOI":"10.1155\/2021\/6613392","type":"journal-article","created":{"date-parts":[[2021,2,25]],"date-time":"2021-02-25T03:05:05Z","timestamp":1614222305000},"page":"1-9","source":"Crossref","is-referenced-by-count":3,"title":["A New Password- and Position-Based Authenticated Key Exchange"],"prefix":"10.1155","volume":"2021","author":[{"given":"Jia","family":"Fan","sequence":"first","affiliation":[{"name":"Sichuan Innovation Center of Industrial Cyber Security, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7225-3846","authenticated-orcid":true,"given":"Lanfei","family":"Qiao","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Southwest Jiaotong University, Chengdu 610000, China"},{"name":"Science and Technology on Communication Security Laboratory, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunfei","family":"Cao","sequence":"additional","affiliation":[{"name":"Science and Technology on Communication Security Laboratory, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shanglin","family":"Liu","sequence":"additional","affiliation":[{"name":"Sichuan Innovation Center of Industrial Cyber Security, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenke","family":"Zhang","sequence":"additional","affiliation":[{"name":"Sichuan Innovation Center of Industrial Cyber Security, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Tang","sequence":"additional","affiliation":[{"name":"Sichuan Innovation Center of Industrial Cyber Security, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/tit.1976.1055638"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2020.2971254"},{"key":"3","article-title":"Optimized fuzzy commitment based key agreement protocol for wireless body area network","volume":"1","author":"Q.
