Abstract

The invention discloses a file tamper-proofing method and system, a terminal and a trusted cloud platform, and relates to the field of mobile terminal security. The method comprises the following steps: checking key files of an operating system to obtain check values of the key files; encrypting the key files and the check values based on trusted information of the terminal; transmitting the encrypted key files and check values to the trusted cloud platform; and if the terminal determines the exception of the key files or the exception of the key files in response to the trusted cloud platform, giving an alarm prompt to a user to realize tamper proofing of the key files. Through adoption of the file tamper-proofing method and system, trusted information of an operator on the terminal and the trusted cloud platform of the operator are fully utilized to ensure the file security of a terminal user from the underlying layer.

Description

technical field [0001] The invention relates to the field of mobile terminal security, in particular to a file tamper-proof method, system, terminal and trusted cloud platform. Background technique [0002] With the rapid development of the mobile Internet and the powerful functions of smart mobile terminals, more and more users use mobile terminals to process and transmit data, and the security issues of mobile terminals are becoming more and more prominent. The Android operating system is facing severe challenges due to its openness and high market share. [0003] Traditional PC-side and server-side file anti-tampering technologies mainly rely on storing original key files on independent physical storage media and performing regular manual comparisons. [0004] The file anti-tampering technology of the Android terminal is also based on the traditional PC-side and server-side file anti-tampering technology. According to the storage location of the encrypted original key fi...
