    HomeCA: Scalable Secure IoT Network Integration
    (INFORMATIK 2019: 50 Jahre Gesellschaft für Informatik – Informatik für Gesellschaft, 2019) Müller, Robert; Schmitt, Corinna; Kaiser, Daniel; Waldvogel, Marcel
    Integrating Internet of Things (IoT) devices into an existing network is a nightmare. Minimalistic, unfriendly user interfaces, if any; badly chosen security methods, most notably the defaults; lack of long term security; and bugs or misconfigurations are plentiful. As a result, an increasing number of owners operate unsecure devices. Our investigations into the root causes of the problems resulted in the development of Home Certificate Authority (HomeCA). HomeCAincludes a comprehensive set of secure, vendor-independent interoperable practices based on existing protocols and open standards. HomeCA avoids most of the current pitfalls in network integration by design. Long-term protocol security, permission management, and secure usage combined with simplified device integration and secure key updates on ownership acquisition pave the way toward scalable, federated IoT security.

    Researching Financial Market Dynamics through Algorithmic Trading Agents
    (AKWI Jahrestagung 2024, 2024) Helstab, Paul; Mosler, Christof; Kaiser, Daniel
    The evolving landscape of financial markets demands the integration of advanced technologies and quantamental paradigms like market simulations and artificial intelligence. This study explores the use of agent-based interactive discrete event trading simulations to analyze financial market scenarios and detect anomalies. The research involves various market fees and synthetic competition between exchanges, utilizing an inter-market spread arbitrage machine for price stability. This approach enables the observation of anomalies related to spreads, execution speed, traded volumes, liquidity, order execution probability, and agent decision-making influence. This study could serve as a valuable tool for financial institutions and regulatory authorities in strategic decision-making concerning financial market challenges.
