Abstract: A secure cartridge-based storage system includes a set of read/write control electronics on a control board adapted to removably couple with each of a plurality of storage cartridges. The read/write control electronics are adapted to transmit a public key to a target storage cartridge in response to a read/write command received from a host device. The target storage cartridge includes and encryption circuit that authenticates the transmitted public key against a stored public key, accesses a locally-stored encryption key responsive to successful authentication of the public key; and utilizes the locally-stored encryption key to encrypt or decrypt data of the read/write command that is in transit between the storage media and the control board.

Abstract: A secure cartridge-based storage system includes a set of read/write control electronics on a control board adapted to removably couple with each of a plurality of storage cartridges. For each individual storage cartridge, the read/write electronics are adapted to retrieve a unique device identifier from the storage cartridge; retrieve an encryption key stored on the control board in association with the unique device identifier; and utilize the encryption key to encrypt or decrypt data that is in transit to or from a target storage location on the storage media.
