Abstract:
1. A method comprising: encrypting, by chipset encryption hardware of a first platform, data stored on a first storage device of the first platform using a first encryption key; encrypting, by an encryption mechanism other than the chipset encryption hardware, data stored on a second storage device of the first platform using a second encryption key; generating a first migration token; encrypting the first encryption key with the first migration token to generate a first platform-independent migration key; storing the first platform-independent migration key in the first storage device; storing the first migration token in a remote storage location; migrating the first storage device from the first platform to a second platform; retrieving, by the second platform, the first migration token from the remote storage location; decrypting, on the second platform, the first platform-independent migration key with the retrieved first migration token to obtain the first encryption key; and decrypting, on the second platform, the data stored on the first storage device using the first encryption key.
