Abstract

To address the issue of diminished LBS privacy protection capabilities in sparse user environments within vehicular networks, this paper proposed a hybrid privacy protection scheme based on homomorphic encryption. The scheme exploited the properties of homomorphic encryption to enable the on-demand generation and indistinguishable authentication of vehicle users' virtual identities. By obfuscating the virtual addresses with the vehicles' real locations, it further provided hybrid privacy protection based on vehicle identity and location. Security analysis demonstrates that, in addition to effectively preserving service privacy, the scheme is traceable against malicious vehicle identities, and it effectively defends against denial-of-service attacks and pseudonym forgery attacks. Performance analysis results indicate that, compared to traditional pseudonym generation methods and k-anonymity techniques, as the privacy factor k increases to 40, the scheme reduces computational overhead by 25% in dynamic pseudonym generation and achieves over 91% privacy protection, this compensates for the deficiencies of k-anonymity and pseudonym techniques in specific environments, making it more suitable for dynamic, low-latency vehicular network communication environments.
