Latest Patents

One of Gehrer's latest patents is a system and method for improving measurements of an intrusion detection system by transforming one-dimensional measurements into multi-dimensional images. This system includes memory and a processor that is programmed to define a fingerprint, which includes a baseline measurement of a physical attribute during an enrollment period. The system compares runtime measurements to the fingerprint and outputs a multi-dimensional domain image based on the runtime measurement.

Another significant patent is related to microcontroller program instruction execution fingerprinting and intrusion detection. This patent involves monitoring program instruction execution of a microcontroller unit (MCU) through side-channel signal analysis. The process captures a signal trace of a physical property of the MCU, which leaks information correlated with the program instruction execution. Time domain features, frequency domain features, and Mel Frequency Cepstral Coefficients (MFCC) features are extracted to identify an execution signature. A remedial action is performed if the execution signature does not match reference instruction signatures.
