8、n) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be rep

9、resented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards a

10、re drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internatio

11、nal Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16844-5 was

12、prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. ISO 16844 consists of the following parts, under the general title Road vehicles Tachograph systems: Part 1: Electrical connectors Part 2: Recording unit, electrical interface Part 3: Mo

Its purpose is to ensure the compatibility of tachographs from various tachograph manufacturers. The basis of the

15、digital tachograph concept is a recording unit (RU) that stores data related to the activities of the drivers of a vehicle on which it is installed. When the RU is in normal operational status, the data stored in its memory are made accessible to various entities such as drivers, authorities, worksh

16、ops and transport companies in a variety of ways: they may be displayed on a screen, printed by a printing device or downloaded to an external device. Access to stored data is controlled by a smart card inserted in the tachograph. In order to prevent manipulation of the tachograph system, the speed

17、signal sender (motion sensor) is provided with an encrypted data link. A typical tachograph system is shown in Figure 1.

This type of interchange will be

19、used for CAN communication or diagnostic services on CAN (controller area network), where there is need to protect interchanged parameters against fraud. 2 Normative references The following referenced documents are indispensable for the application of this document.

25、to ISO 16844-4. 7 Network layer The network layer shall be implemented according to ISO 15765-2, together with the additional requirements given in ISO 16844-6:2004, 7.1. 8 Application layer The SecuredDataTransmission (hex 84) service according to ISO 14229-1 shall be used. 9 Security sub-layer 9.1

26、 General The security sub-layer is inserted between the application layer and the application, as described in ISO 14229-1. It shall be implemented according to ISO 15764, based on the settings according to ISO 14229-1, giving additional tachograph requirements. The RU shall act as the server accord

ISO 16844-5:2004(E) ISO 2004 All rights reserved 39.2 Security sub-layer service request parameters 9.2.1 Server identifier The server identifier shall be the unique identifier of the RU. If the identifier is less than 8 bytes, it will be padded with hex FF. For a tachograph design

28、ed in accordance with Council Regulations (EEC) No. 3820/85 1and No. 3821/85 2 , last amended by Council Regulation (EC) 1360/2002, the identifier shall be the 8 byte key identifier of the VU in accordance with Council Regulation (EC) 1360/2002, Annex 1B Appendix 11, Section 3.3.1. 9.2.2 Secured mod

29、e service type The RU will only accept the secured mode service types according to Table 1. In all other cases it will send a negative response with error code hex 31 (requestOutOfRange).

30、rding to ISO 14229-1 3 Tachograph service according to ISO 16844-4 and ISO 16844-7 In case of securedModeServiceType 1 the settings of ISO 16844-6 apply for the diagnostic service to be executed in the secured mode. In case of securedModeServiceType 3 the security sub-layer of the RU shall accept a

31、request PGN also for information that is broadcast periodically (see ISO 16844-4), and on reception of a request PGN shall respond without verifying the certificate of the client (see ISO 15764). NOTE The client will send the request in the secured mode to get an authenticated response from the RU.

32、As the messages are available for any client in non-secured mode as well, neither authentication of the client towards the RU nor protection against eavesdropping is needed. 9.2.3 Secured mode service identifier In the case of securedModeServiceType 1, the securedModeServiceIdentifier shall be the 1

33、 byte service identifier (see ISO 14229-1) for the service request of the diagnostic service to be executed in the secured mode. In the case of securedModeServiceType 3, the securedModeServiceIdentifier shall be the PDU format field of the PGN (see ISO 16844-4) of the message to be sent in the secur

34、ed mode. The RU will only accept values of the PDU format field between 0 and 239 (PDU 1 format). In all other cases, it will send a negative response with error code hex 31 (requestOutOfRange). NOTE It is not possible to send the Electronic Engine Controller #1 message to the RU in the secured mode

35、. 9.2.4 Security profile The RU shall only accept security profiles containing the value 0 in the bit number 13 (meaning that the response has to include no user ID). If this bit is set to 1, the RU shall send a negative response with error code hex 40 (auditTrailInformationNotAvailable, see ISO 157

36、64). ISO 16844-5:2004(E) 4 ISO 2004 All rights reserved9.2.5 Audit trail information If the audit trail information of the service request contains the VIN, the RU shall verify it and send a negative response with error code hex 31 (requestOutOfRange), in case it doesnt fit with the VIN stored in th

37、e RU. No other audit trail information contained in the service request shall be verified by the RU. 9.3 Security sub-layer service response parameters In the case of securedModeServiceType 1 in the corresponding service indication, the securedModeServiceIdentifier shall be the 1-byte service identi

38、fier (see ISO 14229-1) for the service response of the diagnostic service to be executed in the secured mode. In the case of securedModeServiceType 3 in the corresponding service indication, the securedModeServiceIdentifier shall be the PDU specific field of the PGN (see ISO 16844-4) of the message

39、to be sent in the secured mode. If no specific response message was requested, the RU will send the acknowledge message in response to the request message.
