Abstract

The invention provides SATA bridge encryption equipment. The SATA bridge encryption equipment is connected with SATA main equipment and SATA slave equipment, the SATA bridge equipment comprises FPGA,and the FPGA is used for performing encryption and decryption on data which is transmitted between the SATA main equipment and the SATA slave equipment and monitoring data and commands between the SATA main equipment and the SATA salve equipment in real time. According to the SATA bridge encryption equipment, encryption and decryption operations can be dynamically configured according to actual demands of users, the data and commands between the SATA main equipment and the SATA slave equipment can be monitored in real time, and parameter information can be monitored and extracted. The SATA bridge encryption equipment has the function of monitoring SATA data and SATA disc parameters simultaneously. Compared with the prior art, the SATA bridge encryption equipment firstly has the function ofdynamic encryption configuration and secondly can monitor the data and hard disc parameters, and the safety performance and flexibility are better.

Description

technical field [0001] The invention belongs to the technical field of chips, and in particular relates to a SATA bridge encryption device. Background technique [0002] In a computer system, storage devices are connected to computers through various interfaces, among which SATA (Serial Advanced Technology Attachment, Serial Advanced Data Attachment Specification) is one of the common interfaces. SATA mainly refers to the connection specification between hard disk drives and computers, which allows users to easily connect hard disk storage devices to computers. SATA has the characteristics of high bandwidth, easy topology expansion, data integrity, reliability, large storage capacity, and hot-swappable support. Currently, traditional SATA master devices and SATA slave devices are directly connected together. The SATA master device (computer) directly controls the reading and writing of the SATA slave device (hard disk). [0003] At present, the existing SATA bridge chips ...
