Abstract:
1. A method to manage encrypted data, comprising: configuring a first portion of a storage medium to store encrypted data, the encrypted data being encrypted using a time-based encryption key; configuring a second portion of the storage medium to include metadata identifying the time-based encryption key, the storage medium being one of a logical unit, a disk drive and a track storage; storing the time-based encryption key separately from the encrypted data and the metadata in a location other than the storage medium, the location being at least one of a cache and a server; receiving a request to store data as encrypted data; encrypting the data using the time-based encryption key; storing the encrypted data in the first portion of the storage medium; generating the metadata to identify the time-based encryption key; storing the metadata in the second portion of the storage medium; receiving a request to read the encrypted data; accessing the metadata to determine the time-based encryption key; and decrypting the data using the time-based encryption key.
