Self-encrypting drives use an encryption engine built into the SSD’s controller to encrypt every file stored on the drive. The purpose of AES Encryption is to convert standard input data known as plaintext to an unintelligible output known as cipher text. So if AES encryption on SSD used for data randomization function only, it only provides some data protection in the sense that if the controller is damaged, a 3rd party would not be able to read the data on the flash. In normal usage, however, there would be no data protection as any party that is in possession of the drive can read the data. Methods of using AES on SSD to Secure Data Hardware-based Encryption Self-encrypting drives include dedicated AES encryption engines that do not require software to run on the host. The randomized AES encryption keys are generated at product initialization using the controller’s true random number generator and encrypted in the SSD. This could also be implemented by a Trusted Platform Modu...
