Problems solved by technology

[0005] The integrity verification method of the memory code in the prior art adopts a single-point verification, which is easily bypassed by HACK. The specific HACK bypasses the HASH of the memory code by modifying the logic of the verified code itself. It can be seen that, Existing integrity check methods for memory codes still have security risks

Abstract

The embodiment of the invention discloses a memory code integrity verification method and device. The method comprises the following steps: sending at least two preset verification codes to a client, so that the client can select a target verification code from the verification codes to verify a designated memory code of the client; acquiring a client verification result returned by the client, wherein the client verification result comprises a returned value and an unique identifier of the target verification code; according to the unique identifier of the target verification code, carrying out matching between the client verification result and a target verification result corresponding to a server; and if the client verification result is identical to the target verification result, determining that integrity verification for the memory code of the client is successful. The method and device provided by the invention has the advantages that a threshold for memory code modification by HACK can be greatly raised, so that the integrity verification accuracy rate for the memory code of the client can be guaranteed, and the safety can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for checking the integrity of memory codes. Background technique [0002] With the enhanced functions of smart mobile terminals, it has become a must-have in people's lives. In order to meet the various needs of users, there are various client application software developed based on smart mobile terminals on the Internet, such as various live video, reading, and game applications. [0003] At present, the core functions of the client software of the terminal device are implemented in the client software code. For example, some client tool software will have some charging functions, and the client logic will judge whether the current user is a VIP user, and only VIP users can use this function. For some HACKs, the implementation logic of this function of the software is reversely analyzed through disassembly, and by modifying the memory code of the proce...
