Abstract
The application relates to an adaptive encryption algorithm dynamic detection method based on an abstract syntax tree, which comprises the following steps: constructing an initial encryption rule library; selecting a public code library, and obtaining a target code library by preprocessing the public code library; dynamically updating the initial encryption rule library to obtain an encryption rule update library; based on the encryption rule update library, performing re-scanning on the target code library to obtain a position set and a relationship graph set; and outputting the position set and the relationship graph set to obtain a detection result of all code sources using an encryption algorithm. By using the method, a self-iterative rule library and a context-sensitive syntax tree analysis engine can be constructed, high-precision positioning and compliance verification of an encryption use scene are realized.
