Abstract

The invention discloses a mobile hard disk password module, and relates to the field of data security. The mobile hard disk password module comprises a USB3.0 interface main control chip, an authentication algorithm chip, an FPGA and a PATA-to-SATA bridge sheet, wherein the USB3.0 interface main control chip is suitable for being connected with a USB interface, and communicates with both the authentication algorithm chip and the FPGA; the FPGA communicates with the PATA-to-SATA bridge sheet; and the PATA-to-SATA bridge sheet is suitable for being connected with storage equipment. The authentication algorithm chip realizes identity authentication; after authentication, user data are encrypted and decrypted through the FPGA, and finally the PATA-to-SATA bridge sheet is used for writing or reading data into or out of storage equipment. The mobile hard disk password module can effectively prevent the data in a storage system from being stolen, tampered or damaged by personnel concerned, so that the completeness and the security of the user data can be guaranteed.

Description

technical field [0001] The invention relates to the field of data security, in particular to a password module of a mobile hard disk. 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. As a storage space for data, the storage system is the last line of defense for data protection. As the storage system develops from local direct connection to networked and distributed, and is shared by many computers on the network, the storage system becomes more vulnerable to attacks. Compared with static storage systems, storage systems connected to the network are often the first choice for attackers, and it is easier to achieve the purpose of stealing, tampering or destroying data. Without storage security precautions, once an attacker successfully infiltrates the data storage system, its negative impact will be immeasurable, s...
