Abstract

The invention discloses a storage device and a data reading method. The storage device comprises a storage control module and a plurality of storage units, the decoding module is used for reading M sub-data from a target storage unit, and the multiple storage units comprise the target storage unit; the selection encryption module is connected with the storage control module and is used for acquiring address information corresponding to the M sub-data from the storage control module and acquiring target address information matched with a preset address in the address information corresponding to the M sub-data so as to output an encryption control signal corresponding to the target address information; and the encryption output module is used for acquiring the M sub-data from the decoding module, encrypting the sub-data corresponding to the target address information when receiving the encryption control signal so as to update the M sub-data, and combining the updated M sub-data into encrypted data to be output. According to the storage device and the data reading method disclosed by the invention, the problem of low data reading safety in the prior art can be solved.

Description

technical field [0001] The invention belongs to the technical field of data security, and in particular relates to a storage device and a data reading method. Background technique [0002] With the advent of the data information age, data security has received more and more attention. But at present, when data is obtained, the data is mostly read directly from the memory, which makes it easy for an attacker to read the program code therein, thereby cracking the internal program. Therefore, the security of data reading is low. Contents of the invention [0003] Embodiments of the present invention provide a storage device and a data reading method, which can solve the problem of low data reading security in the prior art. [0004] In a first aspect, a storage device is provided, including: [0005] a storage control module and a plurality of storage units; [0006] The decoding module is connected to a plurality of storage units, and is used to read M pieces of sub-data...
