ISO 15031-7:2013 pdf download.Road vehicles – Communication between vehicle and external equipment for emissions-related diagnostics -Part 7:Data link security.
This part of ISO 15031 gives guidelines for the protection of road vehicle modules from unauthorized intrusion through a vehicle diagnostic data link. These security measures offer vehicle manufacturers the flexibility to tailor their security to their own specific needs and do not exclude other, additional measures.
This part of ISO 15031 applies to vehicle modules whose solid-state memory contents are able to be altered from outside the electronic module through a diagnostic data communication link. Such alteration could potentially damage a vehicle’s electronics or other components, placing at risk its compliance with government legislation or the vehicle manufacturer’s interests in respect of security.

3 Terms, definitions, and abbreviated terms
For the purposes of this document, the terms and definitions given in ISO 1503 1-2 and the following apply.
3.1 Terms and definitions
3.1.1
unsecured functions
standard diagnostic functions provided by the vehicle manufacturer and controlled and protected by the on-board controller
EXAMPLE Reprogramming of selected items such as the clearing of fault codes.
3.1.2
secured functions
restricted functions whose access requires unlocking the on-board controller
EXAMPLE Programming of vehicle emission systems such as fuel/ignition maps, anti-theft systems, and odometer.
3.1.3
seed
pseudorandom data value sent from the on-board controller to the external test equipment and processed by the security algorithm to produce the key
3.1.4
key
data value giving access to the secured functions sent from the external test equipment to the on-board controller in response to the seed.ISO 15031-7 pdf download.
