Provided in the embodiments of the present application are a dynamic white box-based data processing method, apparatus, and device, the method comprising: using a pre-generated key obfuscation mapping relationship set to perform obfuscation processing on an original key to obtain a redundant key; and inputting the redundant key and to-be-processed data into a white box algorithm library to implement encryption and decryption processing; thus, in the technical solution provided in the embodiments of the present application, different redundant keys can be inputted into the white box algorithm library, so that there is no need to change the white box algorithm library and the key together, increasing the flexibility of the solution.
