Embodiment Construction

[0035] The following will clearly and completely describe the technical solution in this embodiment with reference to the drawings in this embodiment. Obviously, the described embodiment is only a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] In the prior art, in the process of generating the signature, after the image is generated, the image that needs to be signed needs to be imported locally, and the file is manually signed through a script. The existing technology has the problem that the signature must be generated manually after the image is generated, and the implementation process is complicated.

[0037] Such as figure 1 As shown, the embodiment of the present invention provides an integrity measurement method, the method includes: ...

Abstract

The invention discloses an integrity measurement method and device and relates to the technical field of communication. The integrity measurement method and device aim to solve the problem of the prior art that during IMA / EVM signing of a file in a system image, a signature can only be generated after an image is generated, and therefore realization processes are complicated. The method comprises the steps of generating a key pair before ramdisk image compiling, wherein the key pair comprises a public key and a private key; generating an IMA signature and an EVM signature of the file respectively according to file content and the private key during system image generation, and packaging the IMA signature and the EVM signature in the system image. The method and device are applied to integrity measurement.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an integrity measurement method and device. Background technique [0002] With the popularity of smart devices using the Android (Android) system, the security of the Android system has also attracted much attention. Many malicious software obtain user information by tampering or replacing existing files in the system. Ensuring the integrity of files in the system, effectively detecting and preventing access to tampered files is the category of integrity measurement. [0003] The Linux kernel supports integrity measurement, which is generally implemented through an integrity measurement framework (Integrity Measurement Architecture, IMA) module and an extended verification module (Extended Verification Module, EVM). Among them, the basic implementation principle of integrity measurement is: the IMA module makes an IMA signature on the file, that is, makes a summar...
