This document defines the requirements for the secure application module (SAM) used in the secure monitoring compliance checking concept.

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 ENISO17573?1 and the derived suite of standards and Technical Specifications, especially CEN/TS16702?1 and CENISO/TS19299.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.
