Security Credential Management Systems (SCMS)

A system used to secure V2X messages from misuse and enable secure, authentic and private communications. In a V2X system, a digital credential is attached to each wireless message sent between vehicles, the roadside infrastructure, and other travelers. These digital credentials are provided by a third-party and are authenticated by a secure private key. This system is similar to security methods used to secure credit card and other financial transactions over wireless networks.
