Embodiment Construction

[0039] Introduced below are some of the various embodiments of the invention, intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of protection.

[0040] figure 1 It is a flow chart representing the impact backtracking analysis method based on bytecode comparison of the present invention.

[0041] Such as figure 1 As shown, the impact retrospective analysis method based on bytecode comparison of an embodiment of the present invention includes: bytecode input step, bytecode extraction step, bytecode map analysis step, bytecode comparison step and Impact analysis steps.

[0042] Each step is described in detail below.

[0043] (1) Bytecode input steps

[0044] In this step, the first bytecode and the second bytecode are input. The first bytecode can be the bytecode used as sample library input (also referred to as sample library input bytecode). After analysis, the fo...

Abstract

The invention relates to a bytecode comparison based influence backtracking analysis method and backtracking analysis device. The method comprises the following steps of inputting a first bytecode and a second bytecode; extracting and analyzing the input first bytecode and the second bytecode to acquire key information of the first bytecode and key information of the second bytecode; carrying out graphic analysis on the key information of the first bytecode and the key information of the second bytecode to acquire a first graphic analysis result and a second graphic analysis result which represent an association graph of the bytecodes; storing the first graphic analysis result in a bytecode sample library, comparing the first graphic analysis result stored in the bytecode sample library with the second graphic analysis result to acquire a comparison result; and analyzing the influence of a different result according to the comparison result.

Description

technical field [0001] The invention relates to the field of computers, in particular to a backtracking analysis method and a backtracking analysis device for impact analysis based on bytecode comparison. Background technique [0002] Regarding the analysis of the code, there are generally the following types: [0003] (1) Type inference method: Type inference is a process whose purpose is to ensure that each operation is performed on a set of objects with the correct number and type to ensure the validity of the operation. Type inference can check for type errors, choose the appropriate operation, and determine the necessary type conversion according to the situation; [0004] (2) Data flow analysis method: Data flow analysis is a technique used at compile time. It can collect the semantic information of the program from the program code and determine the definition and use of variables at compile time through algebraic methods. Data flow analysis is used It is used to so...
