LDPC Code based Pseudonym Scheme for Vehicular Networks

In this paper, an innovative pseudonym scheme based on Direct Anonymous Attestation (DAA) and Low-Density Parity-Check (LDPC) is proposed. For the sake of improving the efficiency of generating pseudonyms, the proposed scheme uses the LDPC code to encode the credential to produce more available versions. To detect whether a vehicle’s On-Board Unit (OBU) is compromised, the proposed scheme grants t...
