— the calculation of OBM trip data parameters for every OBM trip and other OBM parameters;
— the on-board storage and processing of OBM data across dedicated memory spaces on-board the vehicle;
— OBM data hashing to calculate hash values for specific sets of OBM data. This supports the selection of OBM data for later over-the-air transmission and the verification of the integrity of OBM data.
These aspects are graphically summarised in a flowchart in Appendix 8.
7. Calculation of OBM parameters
7.1.The OBM system shall ensure that the parameters listed in Appendices 2 to 5 (other than those that represent static values) are calculated according to their technical specification and the requirements set out in this paragraph.

— the ‘OBM trip distance’ (parameter 2.2), ‘OBM trip time’ (parameter 2.3) or ‘Idle – time’ (parameter 2.4) reach their maximum values during the OBM trip.
— a new OBM trip is started before the calculation of trip data parameters and hashing of the OBM trip data have been completed.
7.5.When the calculation of OBM trip data parameters has not been completed, data from the trip may be discarded and not be stored on-board the vehicle. Data from discarded trips shall be included in the update of OBM lifetime parameters as defined in paragraph 7.7.
7.6.When the calculation of trip data parameters is complete, the OBM system shall hash the OBM trip data according to paragraph 9.6. The calculation of OBM trip data parameters and hashing of the OBM trip data shall be completed at the latest 10 seconds after the end of the OBM trip.

8.3.3.The OBM system shall monitor whether the queue is full.
— If it is not full, the OBM system shall continue adding subsequent OBM trip data packages until capacity is reached.
— When the ‘OBM OTA queue’ is full the OBM system shall transfer the contents of the ‘OBM OTA queue’ to the ‘OBM OTA outbox’ and clear the contents of the ‘OBM OTA queue’.
8.4. OBM OTA outbox
8.4.1.The ‘OBM OTA outbox’ memory space shall be used to prepare OBM data for over-the-air transmission.
8.4.2.After transferring the contents of the ‘OBM OTA queue’, the OBM system shall append the following additional parameters to the ‘OBM OTA outbox’:
— OBM lifetime parameters from Appendix 3;

8.4.5.After appending these additional data, the OBM system shall perform the hashing of the contents of the OBM OTA outbox according to paragraph 9.8. When a full ‘OBM OTA queue’ triggers the move of new OBM trip data packages to the ‘OBM OTA outbox’ before the ‘OBM OTA outbox’ transmission has completed and was subsequently cleared, the existing ‘OBM OTA outbox’ parameter values shall be deleted before copying in the contents of the more recent ‘OBM OTA queue’.

9.3.Hash values of ‘OBM OTA outbox’ data packages may be used to verify the integrity of the transmission of OBM data from vehicles to authorities.
9.4.Prior to hashing, OBM data must be structured according to the OBM data schemas provided in Appendix 7. For those data parameters defined within these OBM data schemas that are not applicable to the vehicle powertrain type, the OBM system shall fill each unused data byte with a default value of 0xFF.
9.5. OBM hash function
9.5.1.The OBM system shall implement a SHA-256 hashing process to support the hashing operations specified in this Annex. All hashing operations shall be carried out on-board the vehicle in compliance with internationally recognised cryptographic standards to ensure cryptographic robustness, data integrity, and resistance to unauthorised manipulation.
9.6. OBM trip data hashing
9.6.1.Following the calculation of OBM trip data parameters according to paragraph 7.2, the contents of the OBM trip data shall be hashed based on the OBM trip data schema layout specified in Appendix 7 for bytes 0 through to byte 58. The hash function shall be applied to OBM trip data on-board the vehicle only once. After calculation of the hash value for the OBM trip data, no modifications to the OBM trip data package shall be allowed. The ‘OBM trip hash validity status’ byte and ‘OBM trip hash value’ parameter shall not be included in the computation of the hash value.
9.6.2.All reserved data bytes shall be filled with zero values unless otherwise specified.
9.6.3.After calculation of the hash value for the OBM trip data, no modifications to the OBM trip data shall be allowed.
9.6.4.The resulting hash value shall be truncated, preserving the most significant 4 bytes.
9.6.5.Until the hash function computation is finalised, the ‘OBM trip hash value’ parameter shall store a placeholder value of 0xFFFFFFFF and, the ‘OBM trip hash validity status’ shall indicate the hash function computation is incomplete as defined in paragraph 2.9.3.
9.6.6.Once the hash computation is complete, the ‘OBM trip hash value’ shall be updated with the truncated hash value, and the ‘OBM trip hash validity status’ shall be set to indicate the computation of the ‘OBM trip hash value’ is complete. The completed OBM trip data together with the ‘OBM trip hash value’, in the layout specified in Appendix 7, shall be referred to as the OBM trip data package.
9.7. Criterion for OBM trip data selection for later over-the-air transmission (hash condition)
9.7.1.The criterion for OBM trip data package selection for later over-the-air transmission shall be based on the value of the least significant byte of the resulting, truncated ‘OBM trip hash value’. If this value is equal to either 00, 40, 80, or C0, the hash condition shall be considered as fulfilled.
9.7.2.Following the OBM trip data hashing according to paragraph 9.6, the OBM system shall determine whether the ‘OBM trip hash value’ satisfies the hash condition. If the condition is satisfied, the OBM trip data package is selected for OTA transmission.
9.8. OBM OTA outbox hashing
9.8.1.The contents of the ‘OBM OTA outbox’ shall be hashed based on the OBM OTA outbox data schema layout specified in Appendix 7 for bytes 0 through to byte [679]. The hash function shall be applied to the contents of the OBM OTA outbox on-board the vehicle only once. After calculation of the hash value for the OBM OTA outbox, no modifications to the OBM trip data package shall be allowed. The ‘OBM transmission hash validity status’ byte and ‘OBM transmission hash value’ parameter shall not be included in the computation of the hash value.
9.8.2.The resulting hash value shall not be truncated and shall be stored in its full length of 32 bytes.
9.8.3.Until the hash computation is finalised, the ‘OBM transmission hash value’ parameter shall store a placeholder value with each data byte set to a value of 0xFF and the ‘OBM trip hash validity status’ shall indicate the hash function computation is incomplete as defined in paragraph 4.4.
9.8.4.Once the hash computation is complete, the ‘OBM transmission hash value’ shall be updated with the calculated hash value, and the ‘OBM transmission hash validity status’ shall be set to indicate the computation of the ‘OBM transmission hash value’ is complete. The completed ‘OBM OTA outbox’ together with the ‘OBM transmission hash value’, in the layout specified in Appendix 7, shall be referred to as the ‘OBM OTA outbox’ data package.
PART C
