Application: Device for providing analysis capability, method for providing analysis capability, and program for providing analysis capability (Patent ID: US20230418941A1)
The patent filed by Nippon Telegraph and Telephone Corp. describes an analysis function imparting device that acquires execution traces related to branch instructions and memory access by inputting a test script to a script engine. The device then identifies similar sequences within the execution traces, detects function calls as potential type conversion functions, and analyzes variables with input/output relationships to these functions. Additionally, the device performs taint analysis on these variables to detect propagation leakage functions, where tags do not propagate between input and output. It also generates forced propagation rules and imparts a taint analysis function to the script engine based on these rules.
Furthermore, the patent includes claims detailing the components and methods of the analysis function imparting device. These claims outline the circuitry involved in acquiring execution traces, detecting type conversion functions, analyzing input/output relationships, and detecting propagation leakage functions. The device is also capable of setting tags, propagating them based on type conversion functions, and imparting functions to the script engine to ensure proper tag propagation. The method and program described in the patent provide a comprehensive approach to analyzing and imparting functions related to type conversion and propagation leakage within execution traces.
