Abstract
Aspects of the disclosure pertain to a system and method for key wrapping via a storage system to allow secure access to media of the system by multiple authorities with modifiable permissions. The keys used to encrypt ranges of the drive are not stored in plaintext and are recoverable using the credentials of an administrator or user with access to that particular range. An outside attacker cannot recover these keys and a malicious user can only recover the keys to the ranges that user is allowed to access. This is maintained while allowing administrators to modify permissions at any time and, while allowing both administrators and users to change their credentials at any time.
