A critical concern is the problem of malicious vehicle with high-reputation, in which malicious vehicles exploit trust-based security by maintaining legitimate behavioral profiles while strategically injecting malicious content. This behavior creates systemic vulnerabilities that compromise network trust infrastructures. Attacks affecting high-reputation malicious behavior detection include both external and internal types, requiring holistic defense mechanisms. However, current vehicular security research lacks unified defense against both internal and external attacks. Typically, studies that effectively resist internal attackers demonstrate the weaker defense against external attacks, and vice versa. To mitigate these concerns, we have designed a Training Verdict Autonomous Vehicle Networks architecture (TV-AVN) that develops a novel Verdict Misbehavior Detection System (V-MDS) by combining machine learning with reputation mechanism. The proposed scheme incorporates a public key cryptosystem to enhance security during basic safety message transmission. A local authority regularly consolidates detection outcomes to update vehicle reputation scores. In comprehensive experimental comparisons, our approach demonstrates robust-level security performance, with formal verification tools validating the security robustness of our proposed mechanism. For position falsification attacks, our method achieves average detection performance of 0.99\n                    <jats:italic toggle=\"yes\">Precision<\/jats:italic>\n                    , 0.98\n                    <jats:italic toggle=\"yes\">Recall<\/jats:italic>\n                    , and 0.98\n                    <jats:italic toggle=\"yes\">F<\/jats:italic>\n                    1-\n                    <jats:italic toggle=\"yes\">score<\/jats:italic>\n                    . Moreover, the proposed approach demonstrates superior resilience against intelligent attacks involving high-reputation attackers. Although the detection performance experiences degradation, our method remains more stable than existing approaches, which suffer rapid deterioration. In summary, TV-AVN establishes reliable communication for vehicle users, maintaining long-term network quality and preserving user confidence in the system.\n                  <\/jats:p>","DOI":"10.1145\/3801738","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T19:37:54Z","timestamp":1773689874000},"page":"1-26","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["TV-AVN: Training Verdict Based on Random Forest for Misbehavior Detection in Autonomous Vehicle Networks"],"prefix":"10.1145","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1497-3834","authenticated-orcid":false,"given":"Ying Chin","family":"Chen","sequence":"first","affiliation":[{"name":"Information Engineering and Computer Science, Feng Chia University","place":["Taichung, Taiwan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-9729-967X","authenticated-orcid":false,"given":"Wei-Cheng","family":"Lin","sequence":"additional","affiliation":[{"name":"Information Engineering and Computer Science, Feng Chia University","place":["Taichung, Taiwan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3491-5572","authenticated-orcid":false,"given":"Chit Jie","family":"Chew","sequence":"additional","affiliation":[{"name":"Information Engineering and Computer Science, Feng Chia University","place":["Taichung, Taiwan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5487-2318","authenticated-orcid":false,"given":"Yun Yi","family":"Fan","sequence":"additional","affiliation":[{"name":"Information Engineering and Computer Science, Feng Chia University","place":["Taichung, Taiwan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9402-8001","authenticated-orcid":false,"given":"Ngoc Tu","family":"Huynh","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology, Ton Duc Thang University","place":["Ho Chi Minh City, Viet Nam"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7030-2985","authenticated-orcid":false,"given":"Jung-San","family":"Lee","sequence":"additional","affiliation":[{"name":"Information Engineering and Computer Science, Feng Chia University","place":["Taichung, Taiwan"]},{"name":"Cybersecurity Technology Institute, Institute for Information Industry","place":["Taichung, Taiwan"]},{"name":"Faculty of Information Technology, Ton Duc Thang University","place":["Taichung, Taiwan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2026,4,27]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.7551\/mitpress\/9780262042482.003.0023"},{"key":"e_1_3_1_3_2","unstructured":"Iea. 2025.
