This part 2, the trusted recorder is the second part of the standard suite of the secur

22、e monitoring for autonomous toll systems. The overall concept of secure monitoring is defined in part one, CEN/TS 16702-1:2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for i

23、dentifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to a

PD CEN/TS 16702-2:2015CEN/TS 16702-2:2015 (E) 5 Introduction The widespread use of tolling requires provisions for users of vehicles that are roaming through many different toll domains. Users should be offered

26、a single contract for driving a vehicle through multiple toll domains and those vehicles require onboard equipment (OBE) that is interoperable with the toll systems in these toll domains. Thus, there is a commercial and economic justification both in respect of the OBE and the toll systems for enabl

27、ing interoperability. In Europe, for example, this need has been officially recognized and legislation on interoperability has been adopted (see directive 2004/52/EC) and the associated commission decision. The Technical Specification “Electronic fee collection Security framework” (CEN/TS 16439) pro

28、vides an overview of general security requirements of the stakeholders and provides a comprehensive threat analysis for the assets in an interoperable EFC scheme. A number of identified threats may result into less revenue of the Toll Charger, undercharging and/or not meeting required service levels

29、 between the Toll Service Provider and the Toll Charger. Some of these threats can be eliminated by implementing the security measures specified in CEN/TS 16439. However, most of the security measures necessary to combat the identified threats are to be addressed and specified in other standards. On

30、e example of threats that cannot be mitigated by security measures specified in CEN/TS 16439 concerns the trustworthiness of Toll Declarations in autonomous toll systems. Toll declarations are statements that a vehicle has been circulating in a particular toll domain within a particular time period.

31、 In autonomous toll systems, the circulation of vehicles is measured by Toll Service Providers, using GNSS-based OBE. Toll service providers then send Toll Declarations to the Toll Charger, based on which the Toll Charger will charge the Toll Service Provider. The correctness and completeness of the

32、se declarations is obviously of paramount interest to Toll Chargers, Toll Service Providers and users alike. The secure monitoring compliance checking concept provides a solution that allows a Toll Charger to check the trustworthiness of the Toll Declarations from a Toll Service Provider, while resp

33、ecting the privacy of the user. This concept is defined in two Technical Specifications. CEN/TS 16702-1:2014 “Secure monitoring for autonomous toll systems Part 1: Compliance checking” gives the full description of the secure monitoring compliance checking concept. The current Technical Specificatio

34、n, CEN/TS 16702-2 “Secure Monitoring for autonomous toll systems Part 2: Trusted recorder” defines the Trusted Recorder, a secure element required for some of the different types of secure monitoring compliance checking defined in CEN/TS 16702-1:2014.

35、Figure 1 Relation between EFC - Security framework and the overall secure monitoring concept Figure 1 shows the relations between the CEN/TS 16439 EFC Security Framework and EFC Secure monitoring for autonomous toll systems, i.e. the two parts Compliance Checking and Trusted Recorder. The threat ana

36、lysis in the Security Framework motivates the security requirements of an EFC system. The requirements are implemented and fulfilled by several security measures. One of these measures is Secure Monitoring, specified in “Secure Monitoring for autonomous toll systems Part 1: Compliance checking”. The

37、 “Secure Monitoring for autonomous toll systems Part 2: Trusted Recorder” specifies the cryptographic services necessary for the secure monitoring compliance checking concept. Figure 1 indicates also that a Trusted Recorder will most likely be implemented on trusted hardware, e.g. on Secure Applicat

38、ion Module (SAM), inside the OBE or on a general trusted platform of a vehicle. Such a trusted device could support more functions, which may be required for EFC or other services. PD CEN/TS 16702-2:2015CEN/TS 16702-2:2015 (E) 7 1 Scope This Technical Specification defines the requirements for the S

39、ecure 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 u

40、sed 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 leve

41、ls; 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 wit

42、h 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

43、 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. 2 Normative references The following documents, in whole o
