Abstract
In situations, such as disasters, where the physical protection of data may be compromised, algorithmic protection of such data can be increased in anticipation of the disaster. An off-site mechanism can send a disaster preparation script to computing devices expected to be affected, resulting in the deletion of decryption keys from those computing devices. Once the disaster passes, the off-site mechanism, upon receiving confirmation of the physical integrity of the computing devices, can return one or more decryption keys to the computing devices, enabling access algorithmically protected data. The off-site mechanism can also optionally provide access information that can be used to obtain access to the algorithmically protected data via at least one returned decryption key.
