FDOT SCMS

Project Description: The FDOT Security and Credentials Management System (SCMS) will be used to ensure trusted communications between mobile devices and other mobile devices or roadside devices and protect data they handle from unauthorized access. The system will grant trust credentials to qualified mobile devices and infrastructure devices in the Connected Vehicle Environment so those devices may be considered trusted by other devices that receive trust credentials from the SCMS. The SCMS allows credentials to be requested and revoked and secures the exchange of trust credentials between parties, so that no other party can intercept and use those credentials illegitimately. It provides security to the transmissions between connected devices, ensuring authenticity and integrity of the transmissions. Additional security features include privacy protection, authorization and privilege class definition, as well as non–repudiation of origin.
