Abstract
In one embodiment, method that can be performed on a system, is provided to security implementations for storage devices. In one embodiment, the method comprises providing a separate encryption seed for each of a plurality of separate addressable blocks of a non-volatile storage device, wherein a common encryption method is to encrypt data to be stored on the plurality of separate addressable blocks. In one embodiment, the storage device is a portable storage device. In one embodiment, encryption seed is an Initialization Vector (IV). In one embodiment, the encryption seeds comprise at least one of a media serial number and a logical block address corresponding to the respective block of the non-volatile storage device. In an alternative embodiment, the method further comprises storing at least a part of the separate encryption seed of the separate blocks of the non-volatile storage device within the respective blocks of the storage device.
