Code obfuscation encryption method and device, equipment and readable medium

Abstract

The invention discloses a code obfuscation encryption method. The method comprises the following steps: acquiring position information of all function codes in a to-be-encrypted program; judging whether jumping instructions exist in the corresponding function codes one by one based on the position information; if the jump instruction exists in the function code, storing the jump instruction and corresponding address information into a decrypted data body, and replacing the jump instruction with a breakpoint instruction; and in response to the completion of executing the previous step on all the function codes, generating an encrypted file based on an encryption program obtained by the decrypted data volume and the replacement instruction. The invention further discloses a code obfuscation encryption device, computer equipment and a readable storage medium. The original program process is disassembled through instruction replacement, and the encrypted and protected program is allowed to dynamically restore and disassemble the code during operation, so that the problem that the program is cracked due to the fact that a cracker stores the complete program code is prevented, and the security of the program is improved.

Description

Technical field [0001] The present invention relates to the field of computer and communication technologies, and more particularly to a code confusing encryption method, apparatus, device, and readable medium. Background technique [0002] With the rapid development of Internet client technology, the various technologies of the client are increasing, and the functions are more complicated, but because the client code is running on the user terminal, the attacker is easy to read, analyze and crack, Bringing a variety of risks to the system. [0003] Obfuscated code is also known as flower instructions, is a behavior that converts the code of the computer program into a functional equivalent but is difficult to read and understand. The code confuses can be used for program source code, or the intermediate code made in program compilation, and there is also a way of confusing the compilation completed binary code. The program is confused by executing the code is called the code obf...

AI Technical Summary

Problems solved by technology

There are many code obfuscators with different functions: change the names of various elements in the code, such as variables, functions, and classes, into meaningless names, such as rewriting into single letters, or short meaningless letter combinations, Even rewrite it into a symbol like "_", so that readers can't guess its purpose based on the name; rewrite the logical part of the code, and turn it into a functionally equivalent but more difficult to understand form, such as changing the for loop to into a while loop, rewrite the loop into recursion, simplify intermediate variables, etc.; disrupt the format of the code, such as deleting spaces, squeezing multiple lines of code into one line, or breaking a line of code into multiple lines, etc.

[0005] Existing code obfuscation schemes can be cracked by obtaining the original flow through general analysis methods
