SYSTEM AND METHOD FOR CRYPTOGRAPHIC KEY IDENTIFICATION

摘要

A method for determining a cyrptographic key for a MEMS device includes identifying physical properties for the device. A feature vector having a plurality of values is determined. Each of the values correspond to different physical properties. The cryptographic key is determined from the feature vector. The cryptographic key can be determined using a fuzzy extractor. The cryptographic key can be determined using different feature vectors corresponding to different channels in a device or different MEMS structures in the device.
