OPC UA defines several models for these services and has already been deployed by industrial partners in their efforts to achieve I4.0 market readiness and to provide more robust systems. Of particular interest is the security services offered by OPC UA, as they are expected to strengthen the security posture of industrial automation systems, which have so far suffered a number of sophisticated cyber-attacks. In general, cyber-attacks are more severe based on the level of access acquired by the attacker, for example, an attacker with unrestricted administrative level access can issue more powerful commands. It is safe to say then that a more stringent access control security concept can offer systems greater protection from unauthorized access. Several access control models exist, which are categorized under two headings discretionary (data owners/users set the access control rules) and non-discretionary (security administrators control the access granted to users). Here, a non-discretionary access control model, namely the attribute-based access control (ABAC) model is compared to the role-based access control (also non-discretionary) typically assumed with OPC UA, to ascertain how a more granular security structure with ABAC could provide additional security advantages for industry.","PeriodicalId":434189,"journal":{"name":"GI-Jahrestagung","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130109812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

March 2020 Title: A Discussion About Current Augmented Reality Concepts Which Help Users Better Understand and Manipulate Robot Behavior Author: Kai Groetenhardt (kai.groetenhardt@hs-rm.de) Affiliation: Faculty of Design, Computer Science, Media | Hochschule RheinMain, University of Applied Sciences |Wiesbaden | Germany Abstract: Looking at the active research in robotics it is imaginable that robots will increasingly find their way into private households. Therefore, it seems important that humans without technical background are able to understand the behavior of robots and can control them. One obstacle is that humans and robots have different perceptual spaces which are just partly overlapping. Not every action a human can perform lands in the perceptual space of a robot and a robot cannot reach every form of perception that is available to a human. Furthermore, humans and robots have differing conceptual models of the world; robots use several sensors to collect data of their surroundings and use various routines to interpret it. Sometimes they also need knowledge about the real world which is provided by a knowledge framework. Those different perceptual spaces and different conceptual models of the world are reasons why understanding robot behavior can be difficult for humans.

Sometimes they also need knowledge about the real world which is provided by a knowledge framework. Those different perceptual spaces and different conceptual models of the world are reasons why understanding robot behavior can be difficult for humans. Augmented reality (AR) can be a tool to widen the overlapping parts of the perceptual spaces of humans and robots, hence make understanding robots easier. By sending information to AR devices robots can bring it into the visual perception of humans and humans can use the interaction possibilities of those devices to send commands to the robot. There are already some instances in which AR in combination with robots is used, for example: Using AR to show sensor data like those of a sonar sensor via an AR head mounted display (HMD) for debugging purposes [1]. Using an AR HMD to visualize future movements of a robot arm to detect collisions [2].

Low level predicates control individual sensors and actors, higher level predicates control user-defined robots consisting of several sensors and actors.
