    摘要: Data stored on a removable storage medium such as a tape cartridge can be protected from unauthorized access by storing a password hash value in a protected manner on the storage medium, where the password hash value is generated from a password by a one-way hash function such as SHA-256, so that the password cannot easily be determined from the hash value. A media drive is then equipped with logic for blocking access to the data unless the password is provided. The password is protected from unauthorized access because the password hash value, not the password itself, is stored on the storage medium.
