Abstract
A method is provided for detecting a profiling attack in an electronic device. The method includes causing provisioning of the device with a key and causing key operations using the key. A total key provisions counter value of a total key provisions counter is updated in response to the key provisioning. Also, a counter value of a total operations counter corresponding to a total number of operations is updated using the detected provisioned keys. A predetermined relationship between the total key provisions counter value and the total operations counter value is detected. An indication of the profiling attack is provided in response to the relationship meeting a predetermined criterion. In another embodiment, an electronic device having a total key provisions counter value and a total key operations counter value is provided. A predetermined relationship between the counter values indicates a profiling attack of the electronic device.
