Information processing method and apparatus, electronic device, and storage medium

An information processing apparatus, comprising:

• a sequence acquisition module configured to acquire a challenge sequence of a challenge response pair and generate an original response sequence corresponding to the challenge response pair through a Physical Uncloned Function;
• a first information acquisition module configured to generate a first index parameter according to the challenge sequence and acquire feature bit information in the original response sequence according to the first index parameter;
• a parameter update module configured to convert the challenge sequence to generate a second index parameter and update the first index parameter according to the second index parameter and the feature bit information;
• a second information acquisition module configured to acquire new feature bit information in the original response sequence according to the updated first index parameter;
• and
• a processing module configured to repeatedly generate second index parameters and update the first index parameter according to the second index parameter and latest acquired feature bit information and obtain a plurality pieces of feature bit information to generate a target response sequence according to the plurality pieces of feature bit information.
