Problems solved by technology
Intruders take advantage of this vulnerability to tamper or disguise webpage files in mobile devices, making ordinary users unable to identify them, and taking the opportunity to execute or distribute illegal programs
Existing web file detection includes static detection and dynamic detection, but they all involve monitoring the functions and events triggered when the file is running, without considering the obfuscation technology used by intruders, so the recognition rate of malicious script code is very low, and the existing The detection model uses simulation technology, which consumes too much computing resources on the mobile device side

The invention provides an intelligent device file authentication method. The method includes the steps that feature vectors of script codes in webpage files are extracted and classified, and whether malicious codes exist in the webpage files or not is recognized according to the classification result. A file detection and recognition method is provided, different invasion modes are detected in different classification modes, fuzzy processing is introduced to prevent disguise of the malicious codes, and the detection success rate is increased.
Description
technical field [0001] The invention relates to computer data security, in particular to an intelligent device file authentication method. Background technique [0002] With the continuous development and popularization of the Internet, various network security incidents emerge in an endless stream, and the entire mobile Internet environment has been seriously threatened, which has brought huge losses to the society. Network security incidents are mostly caused by hackers, and the internal reason is the security loopholes of software or documents themselves. Intruders take advantage of this vulnerability to tamper or disguise webpage files in mobile devices, making it impossible for ordinary users to identify them, and take the opportunity to execute or distribute illegal programs. Existing web file detection includes static detection and dynamic detection, but they all involve monitoring the functions and events triggered when the file is running, without considering the o...
