Abstract
Apparatus and method for controlling access to protected functionality of a data storage device. In some embodiments, a plurality of identification (ID) values associated with a data storage device are combined to form a combined ID value. The combined ID value is cryptographically processed using a secret symmetric encryption key in combination with a hash function or a key derivation function to generate a unique device credential for the data storage device. The unique device credential is used as an input to a selected cryptographic function to control access to a protected function of the data storage device.
