Abstract
During a pre-boot cycle of a device an algorithm is obtain from a first portion of the hard drive. The algorithm is executed to obtain a key. The key is used to decrypt a second portion of the hard drive to obtain a second key. The second key is used to dynamically decrypt a third portion of the hard drive. A new randomly generated version of the algorithm is produced. The new version of the algorithm is stored in the first portion of the hard drive. The new version of the algorithm is executed to produce a new randomly generated version of the key. The new version of the key is used to re-encrypt the second portion of the hard drive having the second key.
