Abstract
Apparatus and method for detecting unauthorized tampering with a data storage device having a housing and a memory. A first identifier value is stored on an external surface of the housing and a second identifier value is stored within the memory. The first and second identifier values are combined in a predetermined order to form a combined identifier value for which a digital signature is generated using a private key, and the digital signature is stored on the storage device. The digital signature, the first and second identifier values, and one or more dummy identification values are retrieved from the storage device and stored in a memory of a verification device, which combines the retrieved first and second identifier values in the predetermined order to generate a retrieved combined identifier value. The storage device is authenticated using the retrieved combined identifier value, the digital signature and a public key.
