A system and method of generating and comparing a fingerprint for an integrated circuit is provided. A sensor module captures electromagnetic emissions from the integrated circuit. A feature extraction module extracts discriminating features from the captured electromagnetic emissions. A classifier training module generates a plurality of authentication fingerprints of the integrated circuit from the extracted discriminating features creating a reference fingerprint template for the integrated circuit. The reference template for the integrated circuit is stored in a database. For authentication, the reference fingerprint template from the database is compared to the generated authentication fingerprint.
