Safety versus security in the automotive domain

The automotive industry is one of many that is currently changing fast. One of the most challenging innovations in the automotive domain in recent years is the development of autonomous cars, where the assurance of safety and security are key.


There are three standards that are essential in the development of an autonomous vehicle:

  • ISO 26262 addresses Functional Safety (FuSa), which is defined as “the absence of unreasonable risk due to hazards caused by malfunctioning behaviour of E/E systems”. Up until the moment when autonomous vehicles appeared on the scene, achieving Functional Safety was the main target in the development of traditional cars.
  • ISO 21448 addresses Safety Of The Intended Functionality (SOTIF), which is defined as “the absence of unreasonable risk due to hazards resulting from functional insufficiencies of the intended functionality or its implementation”. It addresses the new safety challenges that appear when integrating complex algorithms into an autonomous vehicle. The standard does not replace ISO 26262, but rather complements it, so both standards need to be considered in order to assure safety.
  • ISO 21434 addresses cybersecurity for road vehicles. It specifies engineering requirements for cybersecurity risk management in order to make the autonomous vehicle robust against malicious external attacks.


This speech will present the challenges for integrating cybersecurity, Functional Safety and SOTIF objectives when developing a product for an autonomous car.

Hans Martínez Radl is a member of the Dependability and Safety department at GMV.

He holds a Bachelor’s degree in Mathematics and a Master’s degree in Industrial Mathematics by the USC (Universidade de Santiago de Compostela), Spain. He has over 4 years of experience in Dependability and Safety Engineering in aerospace and in automotive projects, especially in the field of GNSS.

In the aerospace domain he has fulfilled the role of RAMS Manager, mainly for Satellite Ground Segment projects.

In the automotive domain he has worked as a Functional Safety Manager in several projects that were related to autonomous driving, for which his deep knowledge of the ISO26262 and ISO21448 standards has been key.
