Dynamic Security and QoS Adaptation in Real-Time Embedded Systems

Overview A number of Real-Time Embedded Systems (RTESs) are used to manage critical infrastructure such as electric grids or C4I systems. In these systems, it is essential to meet deadlines, for example, to avoid a power outage or loss of a life. The importance of security support is also in-creasing, because more RTESs are being networked. To securely transmit sensitive data, e.g., a battle field status, across the network, RTESs need to protect the data via cryptographic techniques. However, security support may cause deadline misses or unacceptable QoS degradation. As an initial effort to address this problem, the security support in RTESs is formulated as a QoS optimization problem.
