The application of intelligent transport systems (ITS) transmits data with road-to-vehicle communication (RVC) and inter-vehicle communication (IVC). Digital signature is essential to provide security for RVC and IVC. The public key certificate is used to verify that a public key belongs to an individual prover such as user or terminal. A certificate revocation list (CRL) is used for verifying validity of the public key certificate. A certificate authority (CA) publishes a CRL and distributes it to vehicles. CRL distribution traffic disturbs ITS application traffic because of sharing wireless channel between them. To distribute it on low frequency transmission will help to ease the disturbance. This paper proposes a CRL distribution scheme based on random network coding to reduce a non-innovative packet that cannot be used to decode. The simulation results show that the number of non-innovative packet of the proposed scheme is less than that of a simple network coding-based scheme and error correction-based schemes, and the proposed one can distribute CRL to more vehicles than them.
