Problems solved by technology

[0009] However, the use of virtual machine execution method also has certain defects. Specifically, when the interpreter and bytecode of an application are reversed, the use of virtual machine execution method will completely lose the protection function.

Abstract

The invention discloses an instruction execution and dynamic compiling method and device and electronic equipment. The execution method comprises the steps that after a client receives an operation instruction, if the operation instruction is a set instruction, the operation instruction and attribute information corresponding to the operation instruction are sent to a server side, the server sidecompiles a source code of the operation instruction to obtain an original byte code file, the attribute information and/or automatically-generated random information are used for encrypting the original byte code file to obtain a target byte code file and a corresponding interpreter, the client obtains the target byte code file and the interpreter corresponding to the target byte file from a server side, the target byte code file is interpreted through the interpreter, and the operation instruction is executed. The byte code file for executing the instruction and the corresponding interpreterobtained by the client have the high randomness, the instruction code safety is greatly improved, and the problem that the byte code file is cracked is effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of program security protection, and more specifically, the present invention relates to a method for executing instructions on a client side, a method and device for dynamically compiling instructions on a server side, and electronic equipment. Background technique [0002] With the development of decompilation technology, compiled programs can be easily reversed. In order to further improve the security of applications and increase the difficulty of reverse engineering, major manufacturers have developed virtual machine execution methods. [0003] Using the virtual machine execution method mainly includes two parts: [0004] (A) Compiler [0005] A custom compiler compiles the source code into a bytecode file, which uses a custom format and cannot be run directly on the processor. [0006] (B) Interpreter [0007] The bytecode file needs an interpreter to interpret it. The interpreter is a progr...
