Sustainable and Round-Optimized Group Authenticated Key Exchange in Vehicle Communication

Vehicle authentication is an essential component validating the vehicle’s identity and ensuring integrity of transformed data for intelligent transport vehicles (ITS) in vehicular ad hoc network (VANET). Easy to deploy operate privacy-enhancing vehicle mechanisms are mainstay widespread ITS VANET. Very recently, VANET security architectures constituting by IEEE 1609.2 group, NoW project, SeVeCom project. However, these approaches heavily depend on consuming public key infrastructure (PKI) certification authorities (CA). In this work, walking along research line, we attempt design protocols with two diverse factors Vehicle-to-Vehicle (V2V) Vehicle-to-Infrastructure (V2I) networks, respectively, without depending stumbling block PKI/CA. addition, a smooth projective hash function (SPHF) (a.k.a., special case designated-verifier zero-knowledge proof system) guarantees any recipient can confirm authenticity received messages knowing factors. Thus, optimize communication round, SPHF used (group) two-factor authenticated exchange (AKE) low-interactive rounds. The proof-of-concept implementation indicates that computation overheads introduced our solution acceptable real-world deployments. proposed approach validated using Bellare-Pointcheval-Rogaway (BPR) model experimental evaluation theoretical analysis.
