Provably Secure with Efficient Data Sharing Scheme for Fifth-Generation (5G)-Enabled Vehicular Networks without Road-Side Unit (RSU)

The vehicles in the fifth-generation (5G)-enabled vehicular networks exchange data about road conditions, since message transmission rate and downloading service have been considerably brighter. shared by are vulnerable to privacy security issues. Notably, existing schemes require expensive components, namely a road-side unit (RSU), authenticate messages for joining process. To cope with these issues, this paper proposes provably secure efficient data-sharing scheme without RSU 5G-enabled networks. Our work included six phases, namely: TA initialization (TASetup) phase, pseudonym-identity generation (PIDGen) key (KeyGen) signing (MsgSign) single verification (SigVerify) batch signatures (BSigVerify) phase. vehicle our has ability verify multiple simultaneously. not only achieves requirements but also withstands various attacks on network. Ultimately, evaluates favourable performance compared other regards costs of communication computation.
