Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The present invention adds an encryption and decryption part on the basis of a common recording optical drive. The encryption and decryption part consists of FPGA (or dedicated chip), TCM, and smart card slot.

[0028] The optical drive designed by the present invention has a smart card slot, and the secret key used for encryption and decryption is stored in the smart card. When using the encryption function, the smart card with the secret key written in advance needs to be inserted.

[0029] When using the optical drive to record, the FPGA is responsible for detecting the data packets transmitted on the SATA (host) bus, intercepting the data written in the op...

Abstract

The invention provides a CD driver with a hardware encryption function, a recording method and a reading method. The CD driver is provided with an intelligent card slot; and when the encryption function is used, an intelligent card, in which a secret key is previously written, needs to be inserted. When the CD driver is used for carrying out recording, an encryption module in the CD driver automatically encrypts recording data; the process is transparent for an operation system and does not need an extra drive program, and the encryption process can be prevented from being damaged by virus programs, so that the safety can be improved and the operation process, for data encryption, of the user can be simplified.

Description

technical field [0001] The invention relates to the field of data protection, in particular to an optical drive with hardware encryption function and a recording and reading method. Background technique [0002] The optical drive is a machine used by the computer to read and write the contents of the optical disc. It is also a relatively common component in desktop computers and notebooks. With the application of multimedia more and more widely, the optical drive has become a standard configuration in many computer accessories. [0003] In industries that require confidentiality work, optical discs are a relatively common storage medium. When there is a need for encryption of the content stored in the optical disc, software encryption is usually used to encrypt the files to be burned using encryption software, and then Then burn to disc. Using this method is easy to cause omission of files. At the same time, the encryption process is software encryption, and there is a risk...
