As technology advances, confidence in autonomous driving hasn’t grown as quickly. Waymo now wants to make a breach.
Waymo has created a security framework. Methods for assessing technical safety and guidance for the Waymo Driver – autonomous driving. Using the approach could Waymo establish themselves in several cities. But that Trust in the technology is still expandable. A blueprint for building trust has now been created.
Creating a safety concept for fully autonomous vehicles is a formal way of explaining how a company determines that an autonomous vehicle system is safe enough to operate on public roads without a human driver. It contains evidence to support this statement and includes an explanation of the system and the methods used for development and validation. It requires high engineering discipline and scientific scrutiny, meaning it includes more detail and context than the usual safety reports from companies developing autonomous vehicles.
The toolkit that Waymo has released can help achieve such consistency and guide us and others in the industry in creating our approach to security. Waymo believes that a security concept should not only state how a system is ready for deployment, but also justify that the set of acceptance criteria is sufficient and the valuation methods used are credible. Uniqueness, according to Waymo, is the definition of assessing the adequacy of a security policy and can be used for industry comparison.
1 A Layered Approach to Security: First, Waymo explains its definition of security and the overall goal of the security concept, which is based on the concept of “absence of undue risk”. Waymo then presents a layered approach to security introduced with the 2020 Framework. It assesses risk assessment for three categories of hazards: architectural, behavioral, and operational hazards during operation. Finally, the framework presents acceptance criteria for security concepts. A concept that anyone can implement to ensure that the acceptance criteria for evaluating their system are appropriate and sufficient.
2 A dynamic approach to security: This is used to determine security regulations. That means ongoing (not one-off) risk assessments and operational readiness assessments.
3 A Trusted Approach to Security: Waymo presents the Argument Credibility Assessment (CCA), which is used to structure arguments. The industry is also involved in this. The CCA rests on two pillars – credibility of arguments and credibility of evidence – which are reinforced by an implementation credibility check.
Together, these three factors allow for a coherent structure to derive claims.
