Abstract
A method of securing a telecommunication terminal that is connected to a module used to identify a user of the terminal is described. The method includes a step including executing a procedure in which the terminal is matched to the identification module, consisting in: securely loading a first software program including a data matching key onto the identification module; securely loading a second software program which can operate in conjunction with the first software program onto the telecommunication terminal; transmitting a data matching key that corresponds to that of the first software program to the second software program; storing the transmitted data matching key in the secured storage zone of the telecommunication terminal; and conditionally submitting every response from the first software program to a request from the second software program upon verification at the true value of the valid possession of the data matching key by the second program.
