The invention discloses a file encryption method and device, a system platform and a file decryption method. The method comprises the steps that a first secret key is determined, and the first secret key is a randomly-generated character string with the preset length; based on a preset transformation rule, transforming the first key to obtain a second key; according to the second secret key and a preset encryption algorithm, the target file is encrypted, the first secret key, the preset encryption algorithm and a preset transformation rule are written into a code segment used for kernel compiling in the target platform, and the first secret key written into the code segment is used for kernel compiling; the preset encryption algorithm and the preset transformation rule are used for decrypting the encrypted target file. According to the method and the device, the technical problem that the secret key is easy to leak due to the fact that the encryption and decryption secret key is not processed for file encryption in the prior art is solved.
Description
technical field [0001] The invention relates to the field of data security, in particular to a file encryption method, device, system platform and file decryption method. Background technique [0002] In the prior art, when encrypting files, the encryption and decryption keys are not processed. If the same key is used all the time without processing, the key is easily leaked, and root file system encryption loses its meaning. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a file encryption method, device, system platform, and file decryption method to at least solve the problem that the key is easily leaked due to the lack of processing of the encryption and decryption keys in the prior art. question. [0005] According to an aspect of an embodiment of the present invention, a file encryption method is provided, including: determining a first key, wherein the fi...
