The invention relates to a method 20 for loading an application. According to the invention, the application is to be loaded from a first device 12 to at least one fleet of at least two second devices 18, 130. During an off-line preparation phase 200, a first device generates 22 a set of at least one key, as a generic keyset, the first device generates 24 an application loading script and secures 26 the application loading script by using the generic keyset. A corresponding first result is a secured generic script. The secured generic script is valid for the at least one second device fleet. The first device stores 28 at least one couple comprising the generic keyset and the secured generic script. During a pre-loading phase 210, the first device generates 212 a keyset loading script and secures 214 the keyset loading script by using at least one specific key relating to a second device, as a second device keyset. A corresponding second result is a secured first specific script. The secured first specific script is valid only for the second device. The first device generates 216 a whole script by appending the secured generic script to the secured first specific script. And, during a loading phase, the first device sends 218 to the second device the whole script. The invention also pertains to a corresponding first device. |
