Abstract:
A method for controlling access to a security module [of a mobile terminal by an application of the mobile terminal is described. The method includes sending by a current application of the mobile terminal a request to access the security module, said access request comprising the current identifier of an applet comprised in the security module. The operating system of the mobile terminal reads a look-up table comprising a set of access control rules, an access control rule comprising the identifier of an applet of the security module associated with a control value for an application of the mobile terminal, said access control rule indicating that said application of the mobile terminal is authorized to communicate with the applet of the security module. A current control value is obtained for the current application from at least one certificate of a developer of the current application and an identifier of the current application, associated with the current application, and the look-up table is searched for an access control rule comprising the current identifier of the applet associated with the current control value, the current application being authorized to communicate with the current applet when the search is positive.
