The underlying mechanism of PUF authentication is the creation of large numbers of input and output pairs, known as challenge-response pairs (CRPs), that are unique to each device. Authentication is granted when the rate of matching CRPs is statistically high enough. To increase the number of possible combinations in the authentication process of the sensor system a multi-PUF architecture may be used, employing both the calibration table and the static RAM (SRAM) cache as sources for PUF challenges and responses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Additional information<\/h2>\n\n\n\n<section  \n    class=\"nau-block nau-block-panels   \" \n

systems from cyberattacks by acting as digital fingerprints to leverage the natural manufacturing variations, allowing cryptographic methods to be implemented on a network. This technology enhances the trustworthiness of the authentication of systems in the network and prevents cyberattacks. A differential system, where two sensors of the same type (one calibrated and the other uncalibrated), can be used as the basis for a PUF.
