However, as an open network where information has to interact frequently, it is difficult to ensure the security of data transmitted in VANETs and protect the privacy of drivers. Many existing information-sharing schemes use complex encryption algorithms to enable secure traffic data sharing. Nevertheless, these schemes are not suitable for VANETs because of their high computational overhead and lack of corresponding tracking mechanisms for malicious vehicles. Therefore, a traffic data security sharing scheme is designed that combines blockchain technology and traceable ring signature algorithms to secure the transmitted messages. The traceable ring signature algorithm is formulated in combination with bilinear pairing, enabling conditional privacy protection instead of traditional ring signature. To improve the efficiency of VANETs, this scheme introduces edge computing technology to reduce the computational burden of Road Side Units (RSUs) by offloading most of the computational tasks to the servers via edge nodes. In addition, we use smart contract to track malicious vehicles. Security analysis and performance comparison show that our scheme is more efficient and secure for drivers than other existing related schemes.<\/jats:p>","DOI":"10.1007\/s12083-023-01532-7","type":"journal-article","created":{"date-parts":[[2023,8,5]],"date-time":"2023-08-05T03:03:11Z","timestamp":1691204591000},"page":"2349-2366","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Traffic data security sharing scheme based on blockchain and traceable ring signature for VANETs"],"prefix":"10.1007","volume":"16","author":[{"given":"Xiaohong","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaming","family":"Lai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ata Jahangir","family":"Moshayedi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,8,5]]},"reference":[{"issue":"3","key":"1532_CR1","doi-asserted-by":"publisher","first-page":"1107","DOI":"10.1109\/TITS.2014.2371455","volume":"16","author":"KC Dey","year":"2014","unstructured":"Dey KC, Mishra A, Chowdhury M (2014) Potential of intelligent transportation systems in mitigating adverse weather impacts on road mobility: A review.
