scope:

This document defines the requirements for the secure application module (SAM) used in the secure monitoring compliance checking concept. It specifies two different configurations of a SAM:

- trusted recorder, for use inside a piece of on-board equipment (OBE);

- verification SAM, for use in other EFC system entities.

This document describes

- terms and definitions used to describe the configurations of the two SAMs;

- operation of the two SAMs in the secure monitoring compliance checking concept;

- functional requirements for the configurations of the two SAMs, including a classification of different security levels;

- the interface, by means of transactions, messages and data elements, between an OBE or front end and the trusted recorder;

- requirements on basic security primitives and key management procedures to support Secure Monitoring using a trusted recorder.

This document is consistent with the EFC architecture as defined in EN ISO 17573-1 and the derived suite of standards and Technical Specifications, especially CEN/TS 16702-1 and CEN ISO/TS 19299.

The following is outside the scope of this document:

- The life cycle of a SAM and the way in which this is managed;

- The interface commands needed to get a SAM in an operational state;

- The interface definition of the verification SAM;

- Definition of a hardware platform for the implementation of a SAM.
