Abstract

A cryptographic Serial ATA (SATA) apparatus comprises a main controller, a SATA device protocol stack, a SATA host protocol stack, and a cryptographic engine. The cryptographic engine is operatively coupled between the main controller and the SATA device and host protocol stacks and configured to provide high-speed cryptographic processing.

Description

technical field [0001] The present invention relates to an encryption / decryption application, and in particular provides an encryption / decryption Serial Advanced Technology Attachment (Serial ATA, or SATA) device and method. The term "ATA" (AT Attachment) refers to the physical, electrical, transmission and command protocols for the internal configuration of the storage device. Among them, the word "AT" is deduced from the introduction of IBM in 1984  Personal Computer (PC) AT (Advanced Technology), which was the most advanced personal computer at that time. Background technique [0002] The Serial Advanced Technology Attachment (Serial ATA, SATA) specification is a high-speed interface used to replace the Parallel ATA. The SATA specification defines three different speeds, that is, the first generation operates at a transfer rate of 1.5 billion bits per second (1.5Gbps), the second generation transfer rate is at 3.0Gbps per second, and the third generation transfer rate ...
