Abstract
Mass storage devices and methods for securely storing data are disclosed. The mass storage device includes a communication interface for communicating with a connected host computer, a mass-memory storage component for storing data, a secure key storage component adapted to securely store at least one master secret, and an encryption-decryption component different from the secure key storage component and connected to the secure key storage component and the mass-memory storage component. The encryption-decryption component may be adapted to encrypt data received from the host computer using an encryption algorithm and at least one encryption key and to write the encrypted data into the mass-memory storage component. The encryption-decryption component may also be adapted to decrypt encrypted data stored in the mass-memory storage component for returning the data to the host computer in response to a read data command from the host computer using a decryption algorithm and at least one decryption key the security of which is protected using a master secret securely stored in the secure key storage component.
