CEN/TS 16702-2:2015 - Electronic fee collection - Secure monitoring for autonomous toll systems - Part 2: Trusted recorder

This Technical Specification 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 an OBE; — Verification SAM, for use in other EFC system entities. The Technical Specification describes — terms and definitions used to describe the two Secure Application Module configurations; — operation of the two Secure Application Modules in the secure monitoring compliance checking concept; — functional requirements for the two Secure Application Modules configurations, 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 Technical Specification is consistent with the EFC architecture as defined in ISO 17573 and the derived suite of standards and Technical Specifications, especially CEN/TS 16702-1:2014 and CEN/TS 16439. The following is outside the scope of this Technical Specification: — The life cycle of a Secure Application Module and the way in which this is managed. — The interface commands needed to get a Secure Application Module in an operational state. — The interface definition of the Verification SAM. — Definition of a hardware platform for the implementation of a Secure Application Module.
