Embodiment Construction

[0021] Some embodiments of the invention are combined with Figures 1 to 9 explained in detail. Additional embodiments, features and / or advantages of the invention will become apparent from the detailed description, or be learned by practice of the invention.

[0022] figure 1 is a schematic block diagram of the real-time data encryption / decryption system 8 for IDE / ATA data transmission. The real-time data encryption / decryption system 8 includes a cryptographic interface 10 , which is coupled between an IDE controller 12 of a host device 16 and an IDE controller 14 of a data storage device 18 during operation. The cryptographic interface 10 is used to perform real-time data encryption / decryption as if there were no transparency during IDE / ATA data transfer between the host device 16 and the data storage device 18 without adversely affecting the overall data transfer efficiency.

[0023] The IDE controller 12 supports the standard full-ATA protocol and includes a conventiona...

Abstract

This invention discloses a data encryption / deciphers system, which comprises a cipher interface coupling connected between the main device and data storage device both contain IDE controller to support full ATA protocol separately; the cipher interface comprises two IDE controllers on side of main device and data storage device both controller support ATA protocol partly, and a cipher engine to combine the two IDE controllers during transferring data for transparent real time cipher computing.

Description

technical field [0001] The invention relates to data encryption / decryption, in particular to a real-time data encryption / decryption system for IDE / ATA data transmission. Background technique [0002] Integrated Drive Electronics (IDE for short) is a standard electrical interface used between a computer motherboard bus and a disk storage device. The IDE has been adopted as the standard of the American National Standards Institute (ANSI), so that the ANSI design of the IDE is an Advanced Technology Attachment (ATA). IDE / ATA is also known as an electronic protocol for transferring data from a computer or host device to a data storage device, or from a data storage device to a computer or host device. There are two data transmission methods used in the IDE: Programmed Input / Output (PIO for short) and Direct Memory Access (DMA for short). In PIO mode, data transfer is activated and performed by the master device or processor. In DMA mode, data transfers are controlled by signa...
