Abstract

A key is determined from a volatile response using circuitry on a device. The volatile resporεe depends on process variations in fabrication of the device. Error control data that depends on the first volatile response can be computed, stored externally to the device, and then used to generate the key using a volatile response using the circuitry on the device. Applications of volatile keys include authentication and rights management for content and software.
