File trusted tamper-proofing method and device and electronic equipment

The invention relates to the technical field of file security. The embodiment of the invention provides a file credible tamper-proof method and device and electronic equipment. The credible tamper-proofing method for the file comprises the following steps: acquiring file information of a file needing to be protected, and writing the file information into a kernel linked list in a kernel through a transmission channel with the kernel; in response to a received file modification instruction, judging whether modification object information of the file modification instruction exists in the kernel linked list or not through a HOOK function preset in a security framework; and under the condition that the modification object information of the file modification instruction exists in the kernel linked list, not executing the file modification instruction. The implementation mode provided by the invention has the advantages of small overhead influence and good decoupling performance while protecting the security of t
