Abstract
Method of secure comparative processing of the type in which a processor of an electronic component compares proof data (EPR, AUTH) that it receives as input with main secret data (CTRL, PIN) stored in said electronic component, characterized in that the processor implements, in addition to the comparison with the secret data (CTRL, PIN), complementary operations on the proof data (EPR, AUTH) which generate on the electronic component a variation of behavior which is dependent on the proof data (EPR, AUTH) which it receives as input and which is compounded with the behavioral variation related to the comparison with the main secret data (CTRL, PIN).
