“…Safety cases have been widely used in industry, and some authors use the GSN notation for an automotive hall sensor. In fact, several industry related projects have published experiences in this sense such as providing tool suite, industrial experience, and even it has been used for cross reuse .…”

Robot Operating System (ROS) is a middleware for connecting different components of robots. However, its use is becoming more popular in other domains such as in the automotive sector where initial prototypes have been customized and deployed in cars for demonstrating different functional purposes. Nevertheless, ROS has not been yet tested enough to be used in secure and safety environments. For example, in order to strengthen our ROS architecture, we have encrypted the messages within it. Therefore, this paper analyses the impact of Advanced Encryption Standard (AES) encryption mechanism and the functional safety of our prototype. In this sense, we are considering encrypting messages and we assess the timing constraints, as suggested by the ISO 26262, required for assuring a secure communication between components.

“…Safety cases are widely used in safety critical domains, and they are defined as “ A structured argument, supported by a body of evidence, that provides a compelling, comprehensible and valid case that a system is safe for a given application in a given environment ” . Providing a set of grounded arguments is a key part for developing safety case, and it has been uses in critical domains.…”

Nowadays, security and safety aspects are two of the major concerns for any software system development, especially while developing safety critical systems. This is especially relevant for very small entities because they have a limited amount of resources for dealing with all these aspects at the same time. In addition, these systems are highly regulated domains, and they involve a huge set of standards focused on safety and security‐related issues. Therefore, these small entities are not only facing hurdles related to technical aspects but also from the so‐called technical debt when overarching a critical development. This paper extends the assurance cases approach by integrating security aspects within the life cycle, and it proposes a framework for managing the associated security technical debt for very small entities. A tool chain is outlined, and the approach is illustrated with an industrial use case.
