Title:
ENCRYPTED API USAGE AND ANALYSIS METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/077755
Kind Code:
A1
Abstract:
An encrypted API usage and analysis method and system. The method comprises: acquiring an APK data set, and obtaining an encrypted API call sequence data set according to the APK data set, the encrypted API call sequence data set being constructed on the basis of classification information of a Dalvik instruction (S100); using a training set and a verification set in the encrypted API call sequence data set to train a hidden Markov model and an N-gram model, so as to obtain a trained hidden Markov model and N-gram model (S200); and according to the trained hidden Markov model and N-gram model, performing misuse detection and a usage recommendation operation on the encrypted API (S300). Symbol analysis technology is introduced when the encrypted API call sequence data set of the method is constructed, efficiency of the usage and analysis of the encrypted API is significantly improved, and the effect is better.
