An Enhanced Privacy Preserving, Secure and Efficient Authentication Protocol for VANET

Vehicular ad hoc networks (VANETs) have attracted growing interest in both academia and industry because they can provide a viable solution that improves road safety comfort for travelers on roads. However, wireless communications over open-access environments face many security privacy issues may affect deployment of large-scale VANETs. Researchers proposed different protocols to address VANET, this study we cryptanalyze some the preserving show all existing are vulnerable Sybil attack. The attack be used by malicious actors create fake identities impair protocols, which allows them imitate traffic congestion or at worse cause an accident result loss human life. This vulnerability exists those store vehicle encrypted form, it is not possible search find vehicles. serious nature very prevalent privacy-preserving protocols. To cope with kind attack, propose novel practical protocol uses Public key encryption equality test (PKEET) without leaking any information, eventually eliminate approach same time maintains VANET. Our performance analysis indicates outperforms state-of-the-art protocols: beacon generation constant compared linear increase verification shown faster 7.908%. communicational shows size 322 bytes has least overhead other
