Road Vehicles - Functional Safety Audit and Assessment
Method - Part 3: Software Level
1 Scope
This document specifies the requirements and methods for carrying out functional safety audit
and assessment on functional safety-related activities and working achievements of safety-
related electrical / electronic (E/E) systems at the software level, so as to check and judge the
compliance of the development process and working achievements with functional safety.
This document is applicable to safety-related systems containing one or multiple electrical /
electronic (E/E) systems installed on mass production road vehicles other than mopeds.
This document does not apply to specific electrical / electronic (E/E) systems on special-
purpose vehicles, for example, vehicle systems designed for disabled drivers.

6 Software Security Requirements
6.1 Goal
The goal of this Chapter is to carry out audit and assessment of the relevant working
achievements of software security requirements specifications and detailed software and
hardware interface specifications, so as to provide evidence that:
a) Defines or refines software security requirements derived from technical security
concepts and system architecture design specifications;
b) Defines the security-related functions and characteristics required for software
implementation;
c) Refines the software and hardware interface requirements originally defined in
Chapter 6 of GB/T 34590.4-2022;
d) Verifies whether the software security requirements and software and hardware
interface requirements are applicable to software development, and verifies their
consistency with technical security concepts and system architecture design
specifications.
