A method in a secure element (SE), includes the following method steps: obtaining, in the SE, an identity query, in particular a GET IDENTITY command, sent by a network; encrypting, by means of the SE, identity data stored on the SE, in order to generate encrypted identity data using a symmetrical key generated in the SE before the obtaining step; applying, by means of the SE, a message authentication code (MAC) algorithm to the generated encrypted identity data in order to obtain a MAC; and creating and sending a response to the identity query from the SE to the network, wherein the message contains the encrypted identity data and the MAC. An SE is provided for a computer program product, and a system comprising a SE and a network.
