Stable disc controller ID from unstable comparator outputs |
摘要 |
A method for generating a root key is described. Stable bits of a plurality of comparator outputs are identified. The root key is selected from a number of the identified stable bits. A statistically unique value is calculated from the root key using a cryptographically secure function. An identifier of the identified stable bits and the statistically unique value are stored in a memory. |
