  • Publication number: 20210144003
    Abstract: A method for misbehaviour warnings in an intelligent transportation system (ITS) including determining at a network server that an ITS station is misbehaving. In response to determining that the ITS station is misbehaving, the network server transmits a misbehaviour warning message to the ITS station indicating that the ITS station is misbehaving. In response to transmitting the misbehaviour warning message and determining that the ITS station is continuing to misbehave, the network server includes information of the ITS station in a certificate revocation list (CRL) and transmits the CRL.
