Abstract
The invention concerns a method for transmitting to a physical or virtual element of a telecommunications network, an encrypted subscription identifier stored in a security element, or an encrypted identifier of the security element or an encrypted identifier of a terminal cooperating with the security element. The method includes pre-calculating proactively, at the occurrence of an event, the encrypted identifier using a key and storing it in a file or memory of the security element with a parameter enabling the key to be calculated by the element of the telecommunications network, in order to be able to transmit to the element of the telecommunications network the encrypted identifier and the parameter, without having to compute the encrypted identifier when the terminal is asking for it.
