scope:

Specifies the application interface in the context of Electronic Fee Collection (EFC) systems using the Dedicated Short-Range Communications (DSRC). This is an interface standard, adhering to the open systems interconnection (OSI) philosophy (ISO/IEC 7498-1), and it is as such not concerned with the implementation choices to be realised at either side of the inerface. This standard provides security-specific functionality as place holders (data and functions) to enable the implementation of secure EFC transactions. Yet the specification of the security policy (including specific security algorithms and key management) remains at the discretion and under the control of the EFC operator, and hence is outside the scope of this European Pre-Standard.
