Abstract
A method for assisting in improving the security of an electronic operation carried out via a secure element. The method comprises the following steps. A first application of the secure element is selected and writes a piece of contextual data in means of recording of the secure element. Then, a second application is selected, reads the contextual data in the means for recording and verifies if the contextual data satisfies a predefined condition. If yes, it is considered that the context of the selecting of the second application is legitimate and the electronic operation can continue normally.
