Abstract
A secure disk drive is disclosed comprising a disk for storing data, and an input for receiving an encrypted message from a client disk drive, the encrypted message comprising ciphertext data and a client drive ID identifying the client disk drive. The secure disk drive comprises a secure drive key and an internal drive ID. A key generator within the secure disk drive generates a client drive key based on the client drive ID and the secure drive key, and an internal drive key based on the internal drive ID and the secure drive key. The secure disk drive further comprises an authenticator for verifying the authenticity of the encrypted message and generating an enable signal, the authenticator is responsive to the encrypted message and the client drive key. The secure disk drive further comprises a data processor comprising a message input for receiving the encrypted message from the client disk drive, and a data output for outputting the ciphertext data to be written to the disk. The data processor further comprises an enable input for receiving the enable signal for enabling the data processor, and a key input for receiving the internal drive key, the internal drive key for use in generating a message authentication code. The data processor outputs reply data comprising the message authentication code. The secure disk drive outputs a reply to the client disk drive, the reply comprising the reply data and the internal drive ID.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
