Static And Dynamic Component Obfuscation On Reconfigurable Devices, Camdon R. Cady
Theses and Dissertations
Computing systems are used in virtually every aspect of our lives. Technology such as smart phones and electronically controlled subsystems in cars is becoming so commonly used that it is virtually ubiquitous. Sometimes, this technology can be exploited to perform functions that it was never intended to perform, or fail to provide information that it is supposed to protect. X-HIA was shown to be effective at identifying several circuit components in a significantly shorter time than previous identification methods. Instead of requiring a number of input/output pairings that grows factorially or exponentially as the circuit size grows, it requires only …

Aphid: Anomaly Processor In Hardware For Intrusion Detection, Samuel A. Hart
Theses and Dissertations
The Anomaly Processor in Hardware for Intrusion Detection (APHID) is a step forward in the field of co-processing intrusion detection mechanism. By using small, fast hardware primitives APHID relieves the production CPU from the burden of security processing. These primitives are tightly coupled to the CPU giving them access to critical state information such as the current instruction(s) in execution, the next instruction, registers, and processor state information. By monitoring these hardware elements, APHID is able to determine when an anomalous action occurs within one clock cycle. Upon detection, APHID can force the processor into a corrective state, or a …
