Wrapper Function for Unified Software Entry Point Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analyzing software applications with multiple entry points is a time-consuming process, often requiring duplicate reviews of similar entry points, as existing static analysis methods typically analyze each entry point independently, leading to inefficiencies.
Innovation Solution
A method and system that generate a wrapper function to call all identified entry points with a specified call depth, treating the wrapper function as a single entry point for analysis, thereby allowing for a comprehensive analysis of the software application without independent analysis of each entry point, using intermediate representations and relevant function identification to construct an informative structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each entry point is analyzed as a separate task in parallel, then comprehensive coverage of all entry points is achieved, but analysis time increases significantly
Solution Approach 1:
The patent merges multiple entry point analyses into a unified analysis by generating a wrapper function that combines all entry points. The wrapper function is then analyzed as a single entity, eliminating the need for separate parallel analyses of each entry point while maintaining comprehensive coverage of all entry points within the merged function.
Solution Approach 2:
The wrapper function serves as a universal analysis target that represents all entry points simultaneously. By analyzing the wrapper function, the system achieves multi-functionality where a single analysis process covers multiple entry points that would otherwise require separate analyses, thereby reducing analysis time while maintaining comprehensive coverage.
2Manufacturing precision
If all entry points are reviewed individually, then complete validation is achieved, but duplicate review points increase analysis complexity
Solution Approach 1:
The patent combines multiple entry points into a single wrapper function, merging their validation requirements into one unified analysis. This eliminates duplicate review points while maintaining complete validation, as the wrapper function encompasses all entry points and their respective validation criteria in a single structured entity.
3Reliability
If multiple tasks are run in parallel for each entry point, then thorough analysis is achieved, but processing overhead increases
Solution Approach 1:
The patent merges multiple parallel task executions into a single processing operation by creating a wrapper function that consolidates all entry points. This unified function is then analyzed in one processing pass, eliminating the overhead of managing multiple parallel tasks while maintaining thorough analysis through the comprehensive wrapper structure.
Data Source
AI summary
The present disclosure provides a system and method for performing an analysis of a software application in a computing environment. A receiving module accepts source code of the software application as input data and obtains a list of the entry points. Intermediate representation from the input data is generated in order to construct informative structure for the software application. Uncalled functions in the software application are identified and are considered as entry points. The entry points are wrapped into one entry point and analyzed maintaining calling context of all the entry points.
