Client program disassembly prevention protection method

Abstract

The invention relates to a client program disassembly prevention protection method, which comprises the following steps of: preprocessing a source code of a client program, and packaging other contents except a basic data interaction service into a plurality of dynamic libraries; performing encryption processing on the plurality of dynamic libraries; storing the encrypted dynamic library in a server; and in the initial stage of communication between the client and the server, sending the dynamic library file of the client to the client subjected to credibility verification by the server . Through the above protection measures, the client program installed in the application terminal only has one lightweight executable program which does not involve any service logic, and the main logic function dynamic library of the client is stored in the server and is dynamically obtained during operation, so that decompilation by a network attacker is fundamentally avoided. The source code constantof the client and the compiled dynamic library are encrypted, so that the client cannot be decompiled again.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a client program anti-disassembly protection method. Background technique [0002] In the application of the C / S architecture, since the client program is deployed on the terminal machine of the user, all users can obtain the executable file and the dynamic link library of the client program. Static disassembly is the most common method for network attacks to understand and master the client, and the constants in the client program are the information that is most likely to be grasped by network attackers. Cyber ​​attackers usually start with static variable information to gradually clarify the client's operating logic, thereby changing the client's logic through disassembly. In this way, the client becomes a springboard for network attackers to attack the server through the client. This attack is often effective and fatal. [0003] Such as figure 1 The attack logic commonly...
