  • Improved real-time Positioning Data through PikeOS-based Augmentation Systems

    When people think of satellite-based GPS, they envision a high-tech satellite navigation system that can pinpoint locations worldwide to within a few meters. But global navigation systems (GNSS) such as the American GPS or the European Galileo struggle with many environmental interferences. So-called satellite-based augmentation systems (SBAS) improve the performance of these navigation systems by correcting their data. From 2022, the Korean peninsula will also benefit from the PikeOS-based SBAS…

  • Verbesserte Echtzeit-Positionierungsdaten durch Augmentierungs-Systeme auf PikeOS-Basis

    Wenn man an Satellitengestütztes GPS denkt, dann hat man ein High-Tech Satelliten-Navigationssystem vor Augen, das weltweit bis auf wenige Meter genau den Standort erkennen kann. Doch Globale Navigationssysteme (GNSS) wie das amerikanische GPS oder das europäische Galileo kämpfen mit vielen Umwelt-Störeinflüssen. Sogenannte Satellite-based Augmentation Systems (SBAS) verbessern die Leistung dieser Navigationssysteme, indem sie ihre Daten korrigieren. Ab 2022 wird nun auch die koreanische…

  • Browsing and Over-the-Air Updates peacefully united

    The electronic systems such as the anti-lock braking system inside a modern car are able to take control of critical systems such as the steering and braking gears. This significantly increases functional safety during vehicle operation, but at the same time also creates the risk of unauthorized access. Consequently, the functional safety of a vehicle must be supported by IT security measures. Real-time applications require deterministic response times, which can only be achieved with the help…

  • Secure Factory Automation

    The continuing technological advancement that is enabling decreasing costs and greater compactness of devices make it possible to connect and control more physical elements in the industrial environment today. This is enabling industrial engineers to monitor processes with greater accuracy and drive OEE (Overall Equipment Effectiveness). At the same time separate operational technology (OT) systems are merging with enterprise IT infrastructure. However, this greater connectivity also brings more…

  • Safety Certification of COTS-based Systems in Automotive Applications

    The ISO 26262 safety standard is a specialization of the general IEC 61508 functional safety standard and defines generic (software) applications and generic (hardware) products that can receive independent certification for automotive applications. When building a complex safety system, such commercial-off-the-shelf (COTS) products can be reused, including their existing certification artifacts. With this approach, safety-related electronics can be assembled from pre-certified software and…

  • Safety-Zertifizierung von COTS-basierten Systemen in Automotive-Anwendungen

    Die Sicherheitsnorm ISO 26262 ist eine Spezialisierung der allgemeinen Norm IEC 61508 zur funktionalen Sicherheit und definiert generische (Software-) Anwendungen und generische (Hardware-) Produkte, die eine unabhängige Zertifizierung für Automotive-Anwendungen erhalten können. Beim Aufbau eines komplexen Sicherheitssystems können solche COTS-Produkte (Commercial off-the-Shelf) wiederverwendet werden, einschließlich ihrer bestehenden Zertifizierungsartefakte. Mit diesem Ansatz kann eine…

  • IT Security Architecture for the next Generation of Control and Safety Technology

    With the increasing use of networked digital technologies in safety-critical areas of railway operations, the requirements for cyber security, which must be considered together with functional safety, are growing. In the HASELNUSS project, a safety platform is being developed that allows the joint operation of safety and security applications on one system.

  • IT-Sicherheits-Architektur für die nächste Generation der Leit- und Sicherheitstechnik

    Mit dem zunehmenden Einsatz vernetzter digitaler Technologien in sicherheitskritischen Bereichen des Bahnbetriebs steigen die Anforderungen an die Cybersicherheit (Security), die gemeinsam mit der funktionalen Sicherheit (Safety) betrachtet werden muss. Im Projekt HASELNUSS wird eine Sicherheitsplattform entwickelt, die den gemeinsamen Betrieb von Safety- und Security-Anwendungen auf einem System erlaubt.

  • Easier Development of embedded Linux Applications with ELinOS

    For many years, embedded Linux systems have been used predominantly in networked environments. These systems worked well for a long time - true to the motto "Never touch a running system". However, this inevitably leads to security problems and is accompanied by the fact that, according to the latest Cyber Security Report by Allensbach and Deloitte, managers see a growing threat situation in their IT infrastructures.

  • Real-Time Performance for Multi-Core Designs

    In Multi-Core-Systemen ist kaum vorhersagbar, wie sich die Kerne gegenseitig beeinflussen, wenn auf gemeinsame Ressourcen zugegriffen wird. Bisher wurde sicherheitshalber das gesamte System gesperrt, solange kritische Codesegmente ausgeführt werden. Aber das muss nicht sein, denn das geht auf Kosten des Echtzeitverhaltens.
