A Traceable Self-Generated Pseudonym Scheme in VANETs

Abstract The generation of the pseudonym in vehicular ad hoc networks (VANETs) usually requires participation a trusted center (TA), and it needs multiple interactions with TA. To address these problems, we propose novel traceable self-generated based on non-interactive zero-knowledge proof (NIZK) consortium blockchain VANETs. In our scheme, pseudonyms method is introduced to eliminate excessive communication burden, composed roadside units (RSUs) replace RSUs verify effectiveness OBU’s through consensus mechanism. Multiple trace authorities (TRAs) are designed jointly tracking real identity OBU, which effectively prevents abuse supervision by only supervisor.
