Secure Your Competitive Edge

Automated Driving Systems (ADS) are revolutionizing the automotive industry. With remote monitoring and control, these systems enable safer and more efficient transportation. However, ensuring the safety and security of these sophisticated systems requires a multifaceted approach.

Importance of SOTIF analysis in ADS development

Safety of the Intended Functionality (SOTIF) is key in the development of Automated Driving Systems as standardised in ISO 21448. It ensures that the system operates safely even in scenarios outside its intended use. SOTIF analysis guarantees the identification of hazardous events and potential risk, providing a strong foundation for safe ADS operations.

Overview of Functional Safety analysis

The Functional Safety as per ISO 26262 of an ADS ensures that the system’s processes are secure and reliable. Our team performs Hazard and Risk Analysis, FMEA and FTA, and SOTIF analysis to identify potential hazards and establish the necessary mechanisms to mitigate any risks.

Overview of Cybersecurity analysis

Cybersecurity as per ISO/SAE 21434 is critical for the deployment of Automated Driving Systems. Our Cybersecurity analysis covers a wide range of topics, including network security and data security, which are essential for autonomous vehicles to function safely and securely.

Integration of SOTIF, Functional Safety, and Cybersecurity analysis in ADS development

Our integrated approach ensures that SOTIF, functional safety, and cybersecurity analysis are implemented throughout the entire ADS development life cycle. We enable ADS developers to perform a comprehensive SOTIF, Functional Safety and Cybersecurity analysis in our Integrated Product Security and Safety Application ‘CRISKLE’ allowing for the identification of hazardous events and the mitigation of risk, while at the same time ensuring the highest levels of cybersecurity are in place.

Challenges faced during integration

The integration of SOTIF (Safety Of The Intended Functionality) and cybersecurity in automated driving presents several challenges, including:

  1. Complexity: Autonomous vehicles are complex systems that rely on multiple software and hardware components, making it difficult to ensure both SOTIF and cybersecurity.

  2. Lack of Standards: There are no established industry standards for integrating SOTIF and cybersecurity in automated driving systems, which can lead to inconsistent approaches and a lack of clear guidelines.

  3. Adversarial Attacks: Adversarial attacks are a type of cybersecurity threat that can manipulate the perception of the vehicle’s sensors, leading to incorrect decision making.

  4. Testing and Validation: Testing and validation of SOTIF and cybersecurity in automated driving systems are time-consuming and expensive due to the large amount of data required and the need for advanced testing environments.

  5. Human Error: Human error is a significant risk factor in the integration of SOTIF and cybersecurity in automated driving systems. Human mistakes can result in security breaches or errors in the intended functionality of the vehicle.

  6. Continuous Monitoring: Continuous monitoring of the system is necessary to ensure that both SOTIF and cybersecurity are maintained throughout the lifetime of the vehicle. However, this requires advanced monitoring and reporting capabilities that may not be available in all systems.

Conclusion and future considerations

The integration of SOTIF, functional safety and cybersecurity analysis into ADS development is essential for enabling a safe and secure future of transportation. At our company, we are continuously updating our methods and tools, ensuring that we stay ahead of the curve in this exciting field.
