Abstrakt: Home and Building Automation (HBA) systems use control
networks for accessing devices inside buildings to improve the building's
efficiency, flexibility and control. Typical applications include the control of
lighting, heating, ventilation and air-conditioning. In such systems, a special
device class called Sensors, Actuators and Controllers (SACs) can be be
identified to have the typical characteristics of low-end ES. SACs play an
important role in HBA systems and are often used in large numbers. The
goal of this thesis is to provide general security in low-end ES while still
allowing to run arbitrary and uninspected (and possible erroneous and
malicious) application programs. The system as well as its environment
should be protected against security attacks. Various existing mechanisms
for improving application level security are reviewed and evaluated in terms
of applicability to low-end embedded systems. Suitable mechanisms are
selected and combined into a concept architecture which is introduced as
an efficient and secure solution for providing resistance to any kind of
software-based attack. The feasibility and effectiveness of the architecture is
demonstrated with a Proof-of-Concept (PoC) implementation which was
developed as part of the thesis. The PoC closely resembles the typical
functional profile of a SAC device. A test environment, consisting of an HBA
network, was built and several examples and tests were run. In these tests,
the PoC delivered some interesting and promising results which support the
potential of the proposed architecture.
