Programming mode and mode matching based bug clustering method

A method is used for software vulnerability analysis and belongs to the field of computer program security. The method is a programming mode and mode matching based bug discovery method; all functions in a program can be subjected to unified analysis; according to different key words and API (Application Program Interface) symbols appearing in each function, each function is mapped to a vector space; and dominated programming modes and most preferred programming modes in the functions are extracted with a matrix analysis method. By calculating a Euclidean distance, the functions with similar programming modes are discovered and clustered into one class, and potential bugs similar to known bugs are discovered.
