The SSD master control chip is connected with a host end and connected with the FPGA module through an ONFI interface. The FPGA module is connected with an equipment end through the SATA interface dock. The SSD master control chip is connected with the FPGA module through the ONFI interface, user storage data interaction is achieved, and the encryption and decryption performance of data transmission and storage between the host end and an SATA hard disk is guaranteed.

Description

technical field [0001] The invention relates to a SATA hard disk encryption module and a working method thereof, belonging to the technical field of data storage security. Background technique [0002] With the increasing value of data and the continuous development of storage technology, the importance of storage systems continues to increase, and data has become the core asset. The data stored on the user's local SATA hard disk is often the first choice for attackers to achieve the purpose of stealing, tampering or destroying data. SATA hard disk storage security has become very important. [0003] There are two encryption protection methods for the existing user’s local SATA hard disk. The first method uses software encryption to encrypt the stored data on the file system. The second method is to add a hard disk data encryption card or a data transmission encryption device between the host and the hard disk to realize the encryption and decryption of the SATA hard disk ...
