Dieser Artikel stützt sich auf das vom 13.10.2015 bis 12.01.2016 gemeinsam durchgeführten Praxisprojekt von ORBIT und der Hochschule Bonn-Rhein-Sieg. Thema des Projekts waren die Methodenevaluation und Automatisierung von Auswertungsprozessen. Speziell ging es um die Überprüfung der von ORBIT entwickelten Methodik zur Anforderungsanalyse und Standortbestimmung – dem ORBIT-Navigator.
Effects of Workspace Awareness and Territoriality in Environments with Large, Shared Displays
(2016)
Synchronous cooperative work of multiple collaborators in large, high-resolution display systems comprises such psychological phenomena like workspace awareness and human territoriality. The phenomena and interplay between them can cause a significant impact on human-human and human-environment interaction. In a non-digital environment humans rely on their own physical abilities, utilities, and social protocols to control those phenomena (e.g. close eyes, or use earplugs to reduce workspace awareness; rotate oneself towards collaborators to increase workspace awareness). Digital environments, on the other hand, provide us with a possibility to ease, automate, and unify control processes, thus taking off that burden from users. Yet, we have to understand first, what effects workspace awareness and territoriality have within a collaborative environment. The aim of this doctoral thesis is to investigate effects of workspace awareness and territoriality on users and interaction processes in mixed-focus scenarios of various collaborative settings.
Noncooperative Game Theory
(2016)
With the rising interest in vehicular communication systems many proposals for secure vehicle-to-vehicle commu- nication were made in recent years. Also, several standard- ization activities concerning the security and privacy measures in these communication systems were initiated in Europe and in US. Here, we discuss some limitations for secure vehicle- to-infrastructure communication in the existing standards of the European Telecommunications Standards Institute. Next, a vulnerability analysis for roadside stations on one side and security and privacy requirements for roadside stations on the other side are given. Afterwards, a proposal for a multi-domain public key architecture for intelligent transport systems, which considers the necessities of road infrastructure authorities and vehicle manufacturers, is introduced. The domains of the public key infrastructure are cryptographically linked based on local trust lists. In addition, a crypto agility concept is suggested, which takes adaptation of key length and cryptographic algorithms during PKI operation into account.
