Title: Automatic Generation of Diverse Software Channels by Means of Arithmetic Codes
Abstract: The importance of safety in the automation industry is continuously increasing. Normative requirements result in considerably more effort at both the hardware and software level in order to fulfill functional and safety requirements. Advances of purely functional components cannot be applied easily because of the hardware dependent certification process. This limits the flexibility of hardware and user application. A new concept is needed in this area to overcome these challenges. This lecture introduces a new methodology that uses arithmetic codes to detect hardware errors through software measures, thereby introducing hardware independence, so that the certification process no longer limits the hardware design.
Furthermore, a concept is presented to provide a high-level language like C for safety user applications and to automatically incorporate the safety measures into the user application, thus providing high flexibility for the application program.
Title: Requirements to the Combination of Functional Safety and IT-Security in Automation
Abstract: With the growing risk of attackers aiming at automation systems, security became an important issue in safety critical applications. Safety measures and security measures apply different algorithms to achieve different goals, and their interaction may lead to mutual interference. In the lecture, a combined architecture of safety and security is presented, which employs security algorithms that preserve the validity of safety error models while security goals are achieved without restrictions. The interaction between the selected techniques is analyzed with respect to safety criteria and security criteria as well as efficiency. As solution to fail-safe and secure communication is taken as an example.
