| dc.description.abstract | There are autonomous drones, cars, boats and trains. But what they all have in common is the ability to have various levels of autonomous capabilities. The key mechanism in an autonomous system is situation classification and the decision that follows when an unexpected event occurs. What was previously the human s responsibility, is now in different degrees the systems responsibility, and that it what makes the system more autonomous.
When mentioning the two terms security and safety , in regard to autonomous systems, one might think that there are a specific meaning and purpose for them. The truth is that in the context of autonomous systems, these terms might be associated to different meanings. Therefore, ambiguities might be a challenge in this context.
The Revolt platform is an autonomous boat concept in a small-scale model, developed and implemented by DNV GL. The Revolt is a test platform for an autonomous ferry, in which purpose is to transport cargo with minimal energy consumption and costs associated with it. The Revolt also serve as an early test platform for sensors and control systems dedicated for autonomous vessels.
If the developers of autonomous systems choose to combine security and safety analysis, then there are significant advantages involved. Both the industries and researchers have started to acknowledge the need to fill the gap between these two areas. There has therefore been developed analysis methods in recent times that are designed for that purpose, and can probably be used for analyzing security and safety of autonomous systems.
In this thesis, I explore different methods for ensuring both safety and security on autonomous systems. With a case study on an autonomous boat concept, the Revolt platform, with a focus on comparing different security/safety methods for the Revolt platform and Autonomous Systems in general.
I have published a research paper based on the work of this project at the European Safety and Reliability Conference (ESREL) 2018, which will be held by NTNU. | |
