Using real identities for communication may leak private data, so pseudonyms are commonly used as identity credentials. However, existing anonymous authentication schemes have limitations, including large vehicle storage demands, information redundancy, time-dependent pseudonym updates, and public\u2013private key updates coupled with pseudonym changes. To address these issues, we propose a certificateless strong anonymous privacy protection authentication scheme that allows vehicles to autonomously generate and dynamically update pseudonyms. Additionally, the trusted authority transmits each entity\u2019s partial private key via a session key, eliminating reliance on secure channels during transmission. Based on the elliptic curve discrete logarithm problem, the scheme\u2019s existential unforgeability is proven in the random oracle model. Performance analysis shows that it outperforms existing schemes in computational cost and communication overhead, with the total computational cost reduced by 70.29\u201391.18% and communication overhead reduced by 27.75\u201382.55%, making it more suitable for privacy-sensitive and delay-critical IoV environments.<\/jats:p>","DOI":"10.3390\/sym17071163","type":"journal-article","created":{"date-parts":[[2025,7,21]],"date-time":"2025-07-21T13:59:11Z","timestamp":1753106351000},"page":"1163","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Strong Anonymous Privacy Protection Authentication Scheme Based on Certificateless IOVs"],"prefix":"10.3390","volume":"17","author":[{"given":"Xiaohu","family":"He","sequence":"first","affiliation":[{"name":"School of Computer Science, Weinan Normal University, Weinan 714099, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shan","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Computer Science, Qufu Normal University, Rizhao 276800, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1065-7447","authenticated-orcid":false,"given":"Hua","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science, Qufu Normal University, Rizhao 276800, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chuyan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science, Qufu Normal University, Rizhao 276800, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,21]]},"reference":[{"key":"ref_1","unstructured":"Deng, Y.-K., Zhang, L., and Li, J.
