Abstract :
Intelligent Transport System (ITS) is for resolving traffic accidents and congestion by using information and communications technology. It is important to ensure the reliability of data in ITS. Public key encryption and digital signature are used for data security. Certification authority (CA) issues a certificate for a public key and manages a certificate revocation list (CRL). While a vehicle moves, it cannot always access the network infrastructure such as road side unit (RSU). If the distribution of CRL is slowly, a vehicle cannot verify the validity of a certificate correctly. This paper proposes a CRL distribution scheme by inter-vehicle communication using random network coding in the situations near intersections with high vehicle density.
