Abstract

The invention discloses a flash memory encryption method and device, a computing device and a computer storage medium. The method comprises the following steps: scanning the flash memory; obtaining ciphertext index slices contained in the flash memory according to the scanning result; when it is determined that the obtained ciphertext index fragment conforms to the preset instruction addition rule, adding the instruction content corresponding to the ciphertext index fragment to the common storage node; replacing a ciphertext index slice contained in the flash memory with a copy instruction corresponding to the ciphertext index slice, wherein a copy instruction corresponding to the ciphertext index fragment is used to copy into the common storage node and execute instruction content corresponding to the ciphertext index fragment in the common storage node. The scheme can confuse the reverse compilation logic of flash memory, improve the reverse compilation difficulty of flash memory, and realize the encryption of flash memory. And the volume of the flash memory can be further reduced and the storage power consumption can be reduced.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a flash memory encryption method and device, computing equipment, and a computer storage medium. Background technique [0002] With the continuous development of science and technology and society, the number of various flash memory is also increasing rapidly. However, flash reverse developers or flash reverse products can easily obtain the source code in flash memory through decompilation of flash memory, which makes piracy and repackaging of flash memory emerge in endlessly. [0003] However, the inventor found in the process of implementing the present invention that the above-mentioned method in the prior art has at least the following defects: currently, in the process of decompiling the flash memory, the execution logic of the flash memory can often be easily obtained through reverse compilation; and, Existing encryption methods tend to expand the flash memory after encry...
