![]() The factory-set DEK is itself protected by a static hash value, common to all WD Passport drives, called the KEK 8. The user is then allowed to set an individual password, called the KEK. The DEK is set at the factory (all of the drives tested used a 256-bit DEK). The researchers refer to this as the DEK (Data Encryption Key). Passport drives that use the USB bridge for encryption rely on either AES-128 or AES-256 to create an encryption key.
